  3. aloha

  4. attenuation

  5. amplitude modulation

A Correct answer
Explanation

This is the correct option. In ASK, the amplitude of the carrier signal is changed to create signal element. In ASK, one voltage level represents binary 1 and another voltage level represents binary 0. Thus, ASK that is implemented using only two levels is called binary amplitude shift keying (BASK).
