Much of the 'jaago grahak jaago' campaign is predicated on the impression that routine exposure to apparently ___________ products can have long term pernicious effects.

Correct. Benign means seemingly harmless and the sentence makes perfect sense. The effects of seemingly harmless products have pernicious effects. Pernicious means something subtly harmful. Incorrect. Deleterious means something harmful or injurious. The campaign is run because of exposure to apparently injurious products with pernicious effects, does not make sense. The drive is to make the consumer aware of side effects of seemingly harmless products. So, benign is the correct answer.
