B Correct answer
Explanation

Statement II gives father's current age as 30 and tells us that 4 years ago, the ratio of mother's age to father's age was 12:13. Four years ago, father was 26, so mother was (12/13) × 26 = 24. Therefore, mother's present age is 28. Statement I only provides relationships (father is 8 years older than mother, and married at 28) without giving any current age, making it impossible to determine mother's present age.
