• A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
• B. If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
• C. If Assertion is correct but Reason is incorrect.
• D. If Assertion is incorrect but Reason is correct.

Answer 1

The correct option is A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

Choose the correct alternative.

The given assertion is "If the angles of a quadrilateral are in the ratio $2:3:7:6,$ then the measure of angles are $40º60º,140º,120º$respectively."

The given reason is The sum of the angles of a quadrilateral is $360º.$

The given assertion is correct. and also the statement of reason is also correct.

Hence, both the assertion and reason are correct and Reason is the correct explanation of the assertion.
