Answer 1

The Correct Option is A

“Father of my father” means A's grandfather.
“Grandson of A’s grandfather” refers to A or A’s brother (male in A's generation).
“Wife of that grandson” is either A’s wife or his brother’s wife.
The certain relationship to A is a brother’s wife, which is the sister-in-law.
