解答：

月度变化为：一月从 $\$2.50 \to \$2.00$ ，下降 $\$0.50$ ；二月从 $\$2.00 \to \$4.00$ ，价格上升；三月从 $\$4.00 \to \$1.50$ ，下降 $\$2.50$ ；四月从 $\$1.50 \to \$4.50$ ，价格上升；五月从 $\$4.50 \to \$3.00$ ，下降 $\$1.50$ ；六月从 $\$3.00 \to \$1.00$ ，下降 $\$2.00$ 。

最大下降是 $\$2.50$ ，发生在三月。

所以正确答案是 B。

The price changes month to month are: January $\$2.50 \to \$2.00$ (drop $\$0.50$ ), February $\$2.00 \to \$4.00$ (rise), March $\$4.00 \to \$1.50$ (drop $\$2.50$ ), April $\$1.50 \to \$4.50$ (rise), May $\$4.50 \to \$3.00$ (drop $\$1.50$ ), and June $\$3.00 \to \$1.00$ (drop $\$2.00$ ).

The largest drop is $\$2.50,$ which occurred during March.

Thus, the correct answer is B .
