Phil Bhai,

IMO A makes sense.

According to some botanists, invasive plants are the second most serious threat, after habitat loss, to native species of plants and animals and to the maintenance of biologically diverse ecosystems.

Parallelism is maintained after & before "and".(Look at the italics part).

In B

threat, after habitat loss, to native species of plants and animals and for
maintaining biologically diverse ecosystems


No parallelism Maintained.

I suggest you to always look for parallelism & comparison errors in GMAT real SC questions. Becox GMAC loves them so much. Even in OG, you see how much GMAC loves Comaprison & parallelism.!!

Thankyou gmatmachoman Bhai!
Best-
