What are Assertion and Reason Questions?

Assertion Reason Questions are a type of objective questions asked by CBSE Board in 10th class examinations.

Assertion Reason type questions consist of two statements and four options. The two statements have one assertion and one reason. The first statement is an 'assertion'. Assertion is followed by a 'reason'. Reason is the second statement.

Based on the two statements, assertion and reason, students are to make a choice from the four options which are:

Option A, if both Assertion and Reason are true and Reason is the correct explanation of Assertion.

Option B, if Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

Option C, if only Assertion is true but Reason is false.

Option D, if Assertion is false but Reason is true.

Why should you practise Assertion Reason Questions?

The CBSE class 10 Science question paper would consist of 39 questions in 5 sections. 

  • Section A consists of 20 objective type questions carrying 1 mark each.
  • Section B consists of 6 Very Short questions carrying 02 marks each. Answers to these questions should be in the range of 30 to 50 words. 
  •  Section C consists of 7 Short Answer type questions carrying 03 marks each. Answers to these questions should in the range of 50 to 80 words
