Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

Option B is the correct answer.
Question is 2m=3n ?
Statement I is insufficient:
m≠0 –> clearly insufficient as no info about n.
Statement II is sufficient:
6m=9n –> reduce by 3: 2m=3n, so this statement directly answers the question (so here it doesn’t matter whether m and n are integers). Sufficient.
