The collector current can be calculated using the formula Ic = β*Ib, where β is the current gain of the transistor and Ib is the base current. Since the base current is known to be 150 uA (given in the figure), multiplying it by the current gain of 100 (also given in the figure) will yield the collector current, which is 15 mA. Therefore, choice B, which suggests multiplying the base current by 100, is the best option to calculate the collector current.
