Answer / jaroosh
And the explanation for the above answer is :
union has the size of the biggest type of its member, so
here its size is 4, while structs size is 4 + 4 + 4 = 16,
and arrays size is 1 * 10 = 10.

Answer / ranjeet garodia
Jaroosh u r right while calculating the size...
but if u take size of int as 2 then astruct size will be
2+4+2=8
array = 1*10= 10
so c is correct
if size of int is 4, then
struct size will be 4+4+4= 12
then a is correct.
