90

None of the above
The pattern multiplies each term by consecutively increasing integers: 3, 4, 4, 4, and 3, which is inconsistent. The actual mathematical progression is found by multiplying by 3, 4, 2/3, 18, and 3, which is also inconsistent. The correct logical path matching the options is multiplying by 3, 4, 2/3, 18, 3, so the intended sequence multiplier drops from 4 to 2/3, meaning 120 * 2/3 = 80. The result is 80.
