“Amit is a businessman, so he must be rich”. From which of the following statements does the implication follow?

Correct option is C

Given:
Premise sentence states: Amit is a businessman => Amit is rich. This expresses a rule "being a businessman implies being rich."

Logic Used:
“If P then Q” (P → Q) in categorical form corresponds to the universal affirmative “All P are Q” (i.e., all businessmen are rich).

Solution:
The implication “businessman => rich” is exactly the statement “All businessmen are rich.” Options 1 and 2 are converses/negations and do not follow; option 4 (“Some businessmen are rich”) is weaker than the given implication.

Correct Answer: (c) All businessmen are rich.
