Assertion and Reason on Insect Climbing a Wall

Assertion (A): An insect is climbing up a vertical wall with constant speed then the force applied by the wall on the insect is vertically upwards and equal to its weight.
Reason (R): Friction is a self-adjusting force.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

For an insect climbing at constant speed, the upward friction force component from the wall must balance its weight. Static friction is indeed a self-adjusting force. Both A and R are true statements, and R explains why the friction force can adjust to balance the weight.
