ABoth Assertion and Reason are true and the Reason is the correct explanation of the Assertion
BBoth Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
CAssertion is true but Reason is false
DAssertion is false but Reason is true
Answer: B
Dilute (0.2 percent) phenol is safe enough for living tissue and is an antiseptic, so the Assertion is true. The Reason is also a true statement, but the structure of phenol does not explain why the dilute solution is used as an antiseptic.
