    B

    Explanation:

    It has 2 NH4 molecules and 1 CO3 molecule.

    NH4 has a molar mass of 18g/mol. Since there are two NH4s, it makes up 36g of the (NH4) 2CO3.

    CO3 has a molar mass of 60g/mol. Since there is one CO3, it makes up 60g of the (NH4) 2CO3.

    If you add up 36 and 60, you will get 96g.
