Answer:

D) 16

Step-by-step explanation:

If a set has 'n' elements, then the number of subset is 2ⁿ.

    J = {a,b,c,d}

Here, number of elements (n) = 4

                 Number of subsets  = 2⁴

                                                   = 2*2*2*2

                                                   = 16
