Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

(1) is wrong. 3/2 = 1 (integer arithmetic). (2) is wrong. 3 < 2 = false. (3) is correct. 3 * 4 = 12. (4) is correct. 3 <<2= 12. In binary 3 is 11, now shift the bits two places to the left and we get 1100 which is 12 in binary (3*2*2).
