Assertion:A pair of closely spaced electron and proton behaves like an electrically neutral particle system and do not apply electric force on isolated proton or electron.
Reason: Two types of charges exist in nature, which are opposite to'each other in polarity. These two types of charges have a tendency to cancel the electrical effect of each other. Benjamin Franklin suggested the use of positive and negative signs to represent these two types of charges. We can calculate the net charge of any system by evaluating the algebraic sum of individual charges.

A

If both assertion and reason are correct and reason is a correct explanation of the assertion .

B

If both assertion and reason are correct but reason is not the correct explanation of assertion

C

If assertion is correct but reason is incorrect

D

If assertion is incorrect but reason is correct.
