Assertion Soft steel can be made red hot by continued hammering on it, but hard steel cannot. 

Reason Energy transfer in case of soft is large as in hard steel.

1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
3. If the assertion is true but the reason is false
4. If both the assertion and reason are false

Assertion The center of mass of an electron and proton, when released moves faster towards proton. 

Reason Proton is heavier than the electron.

Assertion A planet moves faster, when it is closer to the sun in its orbit and vice-versa. 

Reason Orbital velocity in orbit of planet is constant.

Assertion A large force is required to drawn apart normally two glass plates enclosing a thin water film. 

Reason Water works as glue and sticks two glass plates.

Assertion The water rises higher in a capillary tube of small diameter than in the capillary tube of large diameter. 

Reason Height through which liquid rise in capillary tube inversely proportional to the the capillary tube.

Assertion A thermoelectric refrigerator is based on the Peltier effect. 

Reason A thermocouple may be used as a radiation detector.

Assertion The pattern and position of fringes always remain same even after the introduction of transparent medium in a path of one of the slit. 

Reason The central fringe is bright or dark depends upon the initial phase difference between the two coherence sources.

Given below are two statements: 

Assertion Corpuscular theory fails in explaining the velocities of light in air and water. 

Reason According to corpuscular theory, light should travel faster in denser media than in rarer media.
