Rupture is a failure in which a material fails abruptly as we know steel possesses a certain ductility and undergoes some deflection and gives a warning before failure so abrupt failure is not possible in RCC structure.
So, the answer D will be correct.
So, the answer D will be correct.

Also to avoid sudden failure because the difference between steel and concrete tension strength. When over load -over stress the cracks appears will be warning.

Rupture of steel is desirable because it gives prior warning before sudden failure so option B can not be answer. Option D is correct answer.

IS 456-2000 Recommends providing certain minimum steel in a RCC beam.
Answer : to provide enough ductility to the beam.
Answer : to provide enough ductility to the beam.

Option D is correct.
To provide enough ductility so that beam can't fail in compression (to avoid sudden failure).
To provide enough ductility so that beam can't fail in compression (to avoid sudden failure).

I think it is to provide enough ductility to the beam. The language of option B is not suitable for answer.

Sometimes minimum steels are provided beam first ductility and second time of rupture and flexure failure.

I think option B is correct because steel is mainly provided to give flexural strength to the concrete.

Concrete is weak in tension, so that concrete is reinforced to resist tension force acting on it.
