文字解答：

花园面积为 $6\cdot8=48$ 平方英尺。

每平方英尺可种 $4$ 株，所以 Carrie 总共可种 $4\cdot 48=192$ 株草莓。

每株平均 $10$ 个草莓，所以总数为 $10\cdot 192=1920$ 。

正确答案是 D。

First, the size of the garden is $6\cdot8=48$ square feet.

Next, since there are $4$ plants per square foot, Carrie can plant $4\cdot 48=192$ plants total.

Finally, since there are $10$ strawberries per plant, Carrie can harvest $10\cdot 192=1920$ strawberries total.

Thus, the correct answer is D.
