The correct answer is

Mother’s mother

Decode the expression J % K # L @ M α N & Z step by step from right to left.

N & Z: N is the brother of Z.

M α N: M is the father of N. Since N is Z's brother, M is also Z's father.

L @ M: L is the wife of M. Since M is Z's father, L is Z's mother.

K # L: K is the sister of L. Since L is Z's mother, K is Z's mother's sister (Z's maternal aunt).

J % K: J is the mother of K. Since K's mother is also the mother of L (Z's mother), J is Z's mother's mother, i.e., Z's maternal grandmother.

Hence, J is Z's Mother's mother.
