Multiple Choice

Assertion (A): Split web is a rail defect due to excessive loading.

Reason (R): It usually occurs due to corrosion at the rail head.

• Both A and R are true, and R is the correct explanation of A

• Both A and R are true, and R is not the correct explanation of A

• A is true,R is false
