Answer:

0xFF

Explanation:

0xff is a computer programming character which is the hexadecimal number FF that has an integer value of 255. It is represented as a binary in 00000000000000000000000011111111 (under the 32-bit integer).

In this case given that 0xFF has a one (1) in bits 0 to 7, thus representing the value, 0xf01000ff, will turn on all 8 LEDs.

Hence, the correct answer is "0xFF"
