Best answer
Correct choice is (a) TTTT

Explanation: A coin has two sides i.e. head (H) and tail (T). When a coin is tossed, we can get either head or tail. When 3 coins are tossed, the possible outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. Option TTTT is possible only when 4 coins are tossed.
