Option (A) Corollaries and option (B) Theorem are correct as the theorem that assertion that has been proven to be true
What is Theorem?
A mathematical proposition or assertion that has been proven to be true is known as a theorem.
We have a statement:
Which of the following require proof in a logical system?
As we know from the definition of the theorem that assertion that has been proven to be true is known as a theorem.
Corollaries and Theorem require proof in a logical system because some types of theorems are called corollaries.
Axioms and postulates are taken for granted; their veracity is presumed to be true.
Thus, option (A) Corollaries and option (B) Theorem are correct as the theorem that assertion that has been proven to be true
