Consumers may not think of household cleaning products to be hazardous substances, but many of them can be harmful to health, especially if they are used improperly.

(A)Consumers may not think of household cleaning products to be

(B)Consumers may not think of household cleaning products being

(C)A consumer may not think of their household cleaning products being

(D)A consumer may not think of household cleaning products as

(E)Household cleaning products may not be thought of by consumers, as

这里的“may not think of”是什么语法现象？

think of sth./sb. to be我觉得也能用

这道题我觉得考点不仅仅在think of 的用法上 而是在指代问题上 如果用consumers 那么后面的but many of them指代的是consumers还是products呢？ 为了避免这样指代不清的情况发生 所以把consumers变为a consumer 这样them就唯一指代products了
