Will go with D.

Last 2 phrases need to be linked using "by".

The skull of the sentence is as follows:

Generals have warned that smoking increases the risk of X, including A and B, and can + Verb in base form + Preposition

=> The last and in the options A and B is not required since there is an AND in the non-underlined portion.

=> Can + Verb in the base form--is the correct grammar. So, E is out.

Comma + VerbING: in the option C is NOT correct because "COMMA + VerbING" modifies the previous "NOUN + VERB".

Answer should be D.

One more for D.

On a side note, Neha, you probably don't need to use the <spoiler> tag to indicate that the OA will be provided later.
I'm really old, but I'll never be too old to become more educated.

OA D -

but when we use "by" - it seems to say that increasing the risk of low birth rate can complicate pregnancy. can you please explain?

Its not low-birth rate. It is low-birth weight. I think this should clear it all.
