Correct answer: B
ptr is initialized with a, so it points to the first element of the array, a[0]. Initially, a[0] is 10.
The expression *ptr += 2 is equivalent to *ptr = *ptr + 2. Therefore a[0] becomes 10 + 2 = 12, and the value of this assignment expression is also 12. The first printf prints 12.
The pointer has not moved; it still points to a[0]. So the second printf also prints 12.
Hence, the output is 12 12.
