This seems confusing.

'a' cannot be the answer because, when the aspen fails to send hormone signals, the roots are no longer suppressed to produce more shoots, and therefore produces more shoots that will outnumber the existing ones. Here the question is other way round..

If periodic regeneration is affected, it will not spread, but will remain whatever they are. Meaning to say, their population is going to remain constant.

I am not able to arrive at any of the choices given. In the passage, from nowhere, coniferous tree details are included in the last sentence, but that does not seem to make any sense to me.

Can someone give a clear explanation and an appropriate answer choice? :?

FOR the same passage i found some more questions: Pls post OA for above and below ques.(if you have)
My take for below 3 questions is C,A,A respectively

The primary purpose of the passage is to explain the
A.qualities that make a particular organism unique
B.evolutionary change undergone by a particular organism
C.reasons that a phenomenon benefits a particular organism
D.way in which two particular organisms compete for a resource
E.means by which a particular organism has been able to survive in a barren region

It can be inferred from the passage that when aspen groves experience a "disturbance", such a disturbance
A.leads to a hormonal imbalance within an aspen clone
B.provides soil conditions that are favorable for new shoots
C.thins out aspen groves that have become overly dense
D.suppresses the formation of too many new aspen stems
E.protects aspen groves by primarily destroying coniferous trees rather than aspens

The author of the passage refers to "the bark of most trees" most likely in order to emphasize the
A.vulnerability of aspens to damage from fire when compared to other trees
B.rapidity with which trees other than aspens succumb to destruction by fire
C.relatively great degree of difficulty with which aspens catch on fire when compared to other trees
D.difference in appearance between the bark of aspens and that of other trees
E.benefits of fire to the survival of various types of trees
