Concept:Question tags repeat the auxiliary verb and switch between positive and negative.
Explanation:The statement "Bakary can lift this heavy log" is positive.
The auxiliary verb used is "can."
A positive statement requires a negative question tag.
So the tag must start with "can't."
The subject "Bakary" is a male person.
Therefore, the pronoun in the tag is "he."
This gives the correct tag as "can't he?"
Options A, C, and D do not use the auxiliary verb "can."
Answer:B. can't he
