Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Surface tension of water is very high (72.7dynes/cm) compared to other liquids.
Reason (R) : High attraction of water molecules for each other is because of H bond.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Water's high surface tension and cohesive properties are essential for soil water movement. Together with adhesion to soil mineral surfaces, they drive the capillary rise of water through narrow soil pores.

Answer 1

The Correct Option is A
