Answer
(b) It is not only dangerous but also illegal to ride a motorcycle without a helmet..
"As well as" and "not only... but also" both join two qualities that are BOTH true, so the conversion is a straight substitution: "It is NOT ONLY dangerous BUT ALSO illegal."
The correlative pair must be completed exactly. Options (c) and (d) write "not only... and", which is not a pairing that exists in English.
Option (a) is the meaning trap: "not dangerous BUT illegal" says it is illegal and NOT dangerous — the opposite of the original, which asserts both. Dropping "only" changes everything.
The four correlatives to learn as a set: both...and, either...or, neither...nor, not only...but also.
It is not only dangerous but also illegal to ride a motorcycle without a helmet..
