Please give explanation as well

Consider the following assembly code: mov 0x8(%ebp), %eax mov (%eax), %edx mov 0xc (%ebp), %eax mov (%eax), %eax add %eax, %edx mov 0x8 (%ebp), %eax mov %edx, (%eax) mov %edx, (%eax) If 0xB (%ebp) and Oxc (%ebp) refer to the function arguments a and b respectively, which one of the following choices represent the C equivalent of the assembly code above? void func(int* a, int* b) {*a = *a + *b; return;} void func(int* a, int* b) {*b = *a + *b; return;} void func(int* a, int* b) {b = a + b; return;} void func(int* a, int* b) {a = b + a; return;} void func(int* a, int* b) {int tmp = *b *b = *a; *a = tmp; return;}
