• B. Both the statements are true and 2 is not the right explanation of 1
• C. Only statement 1 is true
• D. Only statement 2 is true

Answer 1

The correct option is A

Both the statements are true and 2 is the right explanation of 1.

Both the statements are true and statement 2 is the correct explanation for statement 1. The valency of an element is defined as the combining capacity of an element, hence if the valency of an element is 2, it combines with an element of valency one.
