A review of our answer choices shows a split between using “but also” or “they can also” to introduce the second part of our sentence. There is also a split in which verb form we should use (the verb or the -ing form).
When we see a sentence that has “not only” in it and answer choices that include “not only,” it is tempting to ignore everything else and focus only on those options that fit the most common idiom. While “not only X, but also Y” is the most common form of the idiom, “not only X, also Y” is a valid format as well. Many times, “not only, but also” sentences do not include a subject or verb after those words, so it might be tempting to immediately eliminate the choices that start with “they can,” but that could potentially be a mistake. Remember, with “not only, also/but also” constructions, parallelism is key. So we need to start by looking at the portion of the sentence that isn’t underlined:
While they are a popular exotic pet, not only are pythons potentially dangerous to humans if they are large enough, they can also expose their owners to multiple pathogens, including salmonella, leptospirosis, and chlamydia, and increasing the risk of meningitis and sepsis in children.
The sentence reads “not only are pythons potentially dangerous to humans . . .” The structure is “not only” + a verb + the subject. When “not only” is followed by a verb and a subject, then the second clause (the also/but also clause) must also have a verb and subject. Because the verb and subject are not introduced before the “not only,” then the “also” clause must include those as well. While the order is not identical (in the second clause the verb and subject will come before the “also”), the parallelism is still apparent because each clause has the same components.
A. they can also expose their owners to multiple pathogens, including salmonella, leptospirosis, and chlamydia, and increasing
B. they can also expose their owners to multiple pathogens, including salmonella, leptospirosis, and chlamydia, and increase
C. also exposing their owners to multiple pathogens, including salmonella, leptospirosis, and chlamydia, increasing
D. but also expose their owners to multiple pathogens, including salmonella, leptospirosis, and chlamydia to increase
E. but also exposing their owners to multiple pathogens, including salmonella, leptospirosis, and chlamydia, and increasing
We can eliminate options C, D, and E because they do not have a verb and subject. (“Their owners” is the object of the verb expose, not the subject.). In fact, Options C and E don’t even have a verb! An -ing verbal without a helping verb cannot act as a verb, so “exposing” is not a verb.
Beyond the parallelism of “not only, but also,” we need to consider parallelism for the sentence as a whole. The verb in the non-underlined portion is “are dangerous.” This parallels “can expose.” The last verb form choice is “increase” or “increasing.” What is parallel to “dangerous” and “expose”? Increase! Option A uses “increasing,” which is not parallel. It cannot be the best answer.
We have successfully eliminated four answer choices. Option B is the best answer.

While introduces a subordinate clause, hence we need a main clause in the sentence. Thus the use of "they can also" to introduce a main clause is appropriate as against "but also" which will also be redundant as the use of "but" and "while" is not warranted together.
We need the following sentence structure :-
While X, not only are (verb), they can also expose (verb).... and increase (verb)
"Also" has to be followed with whatever followed "not only" - in this case a verb.
Moreover "expose" and "increase" needs to be parallel.
A - Not parallel in the use of "expose" and "increasing"
B - Correct - not only are X, they can also Y and Z - where X, Y and Z are verbs
C - "also exposing" not parallel to "not only are"
D - "expose to increase" shows intention which is not the intended meaning.
E - "but also exposing" is not parallel to "not only are"
