B Correct answer
Explanation

R is grandmother of U, and S is only child of R. Since there are four generations and three married couples, and O is 55, R is likely in the generation above O or the same. Given the family structure and ages, 45 is a reasonable age for R if she is in the generation of O.

AI explanation

S is the only child of R, making R the parent of S, and since R is the grandmother, she belongs to the generation just before S. O is the grandfather who is 55 years old, and because R is the wife of O in this senior generation, her age must be comparable to his. Among the given options, 45 years is the only realistic age for a grandparent in this family structure, while 29 is too young to have a 30-year-old child and 58 is older than her husband, making 45 the only possible answer.
