Solution

The correct option is A 2 and 5
Based on the structure it is clear that the number of lone pairs and bond pairs in hydrazine are 2 and 5 (one lone pair on each nitrogen) and five bond pairs include one bond pair between two nitrogen atoms and four bond pairs between nitrogen and hydrogen atoms.

Hence option C is correct.
