Correct answer: A

To add (4AC)₁₆ and (9BF)₁₆, perform hexadecimal addition digit by digit from right to left. First, add C(12) + F(15) = 27, which is 1B in hex (write B, carry 1). Next, add A(10) + B(11) + 1(carry) = 22, which is 16 in hex (write 6, carry 1). Finally, add 4 + 9 + 1(carry) = 14, which is E in hex. The result is (E6B)₁₆.
