Does the distinguished Member of Parliament really believe that the Indian public is so naive that they will endorse just any stopgap measure? Which fallacy is committed in the above argument?

The rhetorical question is a complex question, loaded with an unproven assumption.

It presupposes that the public is naive and would endorse any stopgap measure.

A complex question smuggles in a claim so that any reply seems to grant it.

The disputed premise is assumed rather than argued for.

Building an unestablished assumption into the question itself is the fallacy of complex question.
