Consider the given statement and decide which of the given assumption is/are implicit in the statement.

Statement:

X did not solve the equation on the black board with a chalk.

Assumption:

I. The equation was solved on a paper.

II. The equation was solved by X on the black board with a marker.

Correct option is D

Given:

Statement: :X did not solve the equation on the black board with a chalk.

Assumption I: The equation was solved on a paper.
The statement does not mention whether the equation was solved at all or where it was solved. The assumption about solving on paper introduces new information that is not implied.
Not implicit
Assumption II: The equation was solved by X on the blackboard with a marker.
The statement does not suggest that X solved the equation at all, nor does it imply what tool might have been used if it were solved. This assumption also introduces new information.
Not implicit.
Conclusion: Since neither assumption follows logically from the statement, the correct answer is option (d): Neither assumption I nor II is implicit.
