Hi Md Raihan Uddin,

The correct answer is D. Let's take a look at the various problems with the other answers.

A. Imported into Massachusetts from Europe in 1869, the gypsy moth was used by a French scientist in an attempt at developing a strong strain of silk-producing insects, crossing gypsy moths with adult silkworms.

"At" is not the correct word or sentence structure; it should be "attempt to [infinitive]."

B. Imported into Massachusetts from Europe in 1869, a French scientist was attempting to develop a strong strain of silk-producing insects by crossing gypsy moths with adult silkworms.

The scientist was not imported!

C. To cross gypsy moths with adult silkworms, in attempting the development of a strong strain of silk-producing insects, a French scientist in 1869 imported the gypsy moth into Massachusetts from Europe.

Wrong structure and placement in the passage.

D. The gypsy moth was imported into Massachusetts from Europe in 1869 by a French scientist attempting to develop a strong strain of silk-producing insects by crossing gypsy moths with adult silkworms.

Correct, hooray!

E. In an attempt at the development of a strong strain of silk-producing insects, a French scientist, importing the gypsy moth from Europe into Massachusetts in 1869 in order to cross gypsy moths and adult silkworms.

Again, wrong use of "at," similar to answer A.

I hope this helps you.
