In Ethernet, the minimum frame size is 64 octets (including the preamble, start frame delimiter, frame header, data, and frame check sequence). Since the data field is only 40 octets long, the frame will be padded with extra octets to meet the minimum size requirement. Therefore, the PAD will be 24 octets long (64 - 40 = 24). The closest answer choice is B, which is 6 octets, but this is not the correct answer.
