Correct option is C
Option (c) contains an error.
Error Explanation:
Its is incorrect. It should be
It’s, which is the contraction of
It is.
Correct sentence: It’s impossible to conduct truly causal research on media consumption and suicide.
Grammatical rule used:
·
It’s = It is (used as contraction)
·
Its = Possessive pronoun (e.g., its color)
· Example: It’s raining today. / The dog wagged its tail.
Information Booster: Never confuse it’s (it is) with its (possessive form of 'it').
