(d) The code is the sum of the numerical positions of the letters in the English alphabet (R=18, U=21, N=14; 18+21+14 = 53. Incorrect. Let's try vowels as multiples of 2 and consonants their position. R=18, u=2*21=42, n=14; 18+42+14 = 74. Incorrect. Let's try position from the end of alphabet. R = 9, u = 6, n = 13; 9+6+13 = 28. Incorrect. Let's reconsider the given codes: run (16), pen (20). r(18)+u(21)+n(14) = 53. p(16)+e(5)+n(14) = 35. Incorrect. Let's try sum of positions divided by some number. 53/3 is not an integer. 35 is not divisible to get 20. Let's try another approach. r=18, u=21, n=14. Sum = 53. Difference between first and last digit is 5-3 = 2. Not 16. p=16, e=5, n=14. Sum = 35. Difference is 3-5 = -2. Not 20. Let's try counting the letters in reverse order. n=13, u=6, r=9. 13+6-9 = 10. Not 16. n=13, e=22, p=11. 13+22-11 = 24. Not 20. Let's try considering only the first and last letter. r=18, n=14. 18-14 = 4. Not 16. p=16, n=14. 16+14 = 30. Not 20. Let's try positions of vowels. For 'run', 'u' is at position 21. For 'pen', 'e' is at position 5. For 'Sun', 'u' is at position 21. This doesn't seem to be a consistent pattern. Let's try the number of letters times some factor. 'run' has 3 letters. 3 * something = 16. 'pen' has 3 letters. 3 * something = 20. Doesn't fit. Let's try assigning numerical values to letters based on their position: r=1, u=2, n=3. Code = 16. p=1, e=2, n=3. Code = 20. S=1, u=2, n=3. Code = ?. This is not working. Let's try another logic. 'run' -> r is 18, u is 21, n is 14. 1+8 + 2+1 + 1+4 = 1+8+2+1+1+4 = 16. 'pen' -> p is 16, e is 5, n is 14. 1+6 + 5 + 1+4 = 1+6+5+1+4 = 17. Not 20. 'Sun' -> S is 19, u is 21, n is 14. 1+9 + 2+1 + 1+4 = 1+9+2+1+1+4 = 18. Not in options. Let's assume the code is based on the position of the first and last letter. For 'run', R is 18, N is 14. 18 - 14 = 4. Not 16. For 'pen', P is 16, N is 14. 16 + 14 = 30. Not 20. Let's try vowels having value 0. r=18, u=0, n=14. 18-0+14 = 32. Not 16. p=16, e=0, n=14. 16-0+14 = 30. Not 20. Let's consider the position of the first and last letter and the number of letters. 'run': R(18), N(14), 3 letters. 18-14 + number of letters * 4 = 4 + 3*4 = 16. 'pen': P(16), N(14), 3 letters. 16+14 - number of letters * 4 = 30 - 12 = 18. Not 20. Let's try position of first and last letter multiplied. 'run': 18 * 14 = 252. Not 16. 'pen': 16 * 14 = 224. Not 20. Let's try sum of positions of first and last letter minus number of letters. 'run': 18 + 14 - 3 = 29. Not 16. 'pen': 16 + 14 - 3 = 27. Not 20. Let's try reverse alphabetical order. 'run': r->9, u->6, n->13. 9+6+13 = 28. Not 16. 'pen': p->11, e->22, n->13. 11+22+13 = 46. Not 20. There seems to be no logical pattern from the given information. Assuming there's a typo in the question or options, or the logic is much more complex, I cannot definitively answer this question.
