Answer: B.
Explanation:
I'm basing my answer on the fact of definitions.
DIRECT PROOF:
A direct proof assumes that the hypothesis of a conjecture is true, then uses logical deductions to prove why its conclusion is true
INDIRECT PROOF:
An indirect proof relies on contradictions to prove a given conjecture, it assumes the conjecture is wrong until it runs into a contradiction that proves it as true.
Based on this
B. An indirect proof begins by assuming that the opposite of what you are trying to prove is true.
