@Anirudh here S has B in its rule should S also be removed???bcoz S is also not terminating, then will S be removed or its rule will be changed, and if we change what will that rule.

@Prashant.

we will remove D, C, B

After all these  the only production of S will also be removed as it contain an useless varaiable B. so I think answer should be 0.

crct me if I am wrong.
