Identify the Awkward or Wrong Expression in Grammar (17-18): Asian Carp and Native Species

The awkward or wrong expression in grammar is in option (d).

The correct sentence should be: 'In order for the native species in the area to survive, the carp population must be consistently held in check.'

The original sentence uses the passive voice ('has to be held') which is grammatically correct but makes the sentence sound a bit clunky. Replacing it with the active voice ('must be held') creates a more concise and direct statement.
