Boolean algebra and Binary number system are different from each other.

Both the Assertion and the Reason are true. Boolean algebra (a system of logic with values 0/1 and operators AND, OR, NOT used to evaluate logical statements) is indeed different from the Binary number system (a positional number system in base 2 used to represent numeric quantities, with arithmetic operators like addition), even though both use only the digits 0 and 1. The Reason correctly explains this: basic logical operations such as AND, OR and NOT are defined and performed only in Boolean algebra, not as standard operations of the binary number system. Answer: (a) Both Assertion and Reason are true, and Reason is the correct explanation for Assertion.
