Do you trust _________________ computers to make the world a better place?
C
Correct answer
Explanation
The correct answer is 'in'. The verb 'trust' takes the preposition 'in' when expressing confidence or belief in someone or something. 'Do you trust in computers to make the world a better place?' correctly uses 'trust in' to express having confidence or faith in computers. 'Trust in' is the standard prepositional phrase. Option A 'trust of' would indicate possession, not the verb. Option B 'trust for' doesn't collocate in this context. Option D 'trust on' is incorrect - 'trust' with 'on' is used in different contexts like 'rely on' or 'count on', not 'trust on'.
