1). Both A and B2). Only B3). Only D4). Both C and D

Answer»

Only D is ERROR free.

Part A must have the verb 'suggested' as with 'have or had', we ALWAYS USE the past participle form of the verb.

Part B must have the preposition 'on' and not 'of' as 'relying' is followed with the preposition 'on.'

Part C has the ARTICLE 'a' missing before the word 'means' as this is a single way of improving food security.

Thus option 3 is the correct answer.
