  • D

Answer

Correct answer:B

Step-by-step solution

Standard Method

Given: Two statements about Morphine are to be checked.

Find: Which option correctly identifies the truth values of Statement I and Statement II.

Statement I: Morphine is a narcotic analgesic, but the claim that it relieves pain without producing sleep is incorrect. Morphine can cause drowsiness and sleep. Therefore, Statement I is false.

Statement II: Morphine and its derivatives are obtained from opium poppy. Therefore, Statement II is true.

Therefore, the correct option is B.

Statement-wise Analysis

Morphine is a narcotic analgesic used for pain relief. However, it also induces drowsiness and may produce sleep, so the statement that it relieves pain without producing sleep is false.

Morphine is obtained from the opium poppy, and its derivatives are also associated with this source. Hence, the second statement is true.

Thus, Statement I is false but Statement II is true, so the correct option is B.

Common mistakes

  • Assuming that every analgesic relieves pain without causing sleep. This is incorrect because morphine is a narcotic analgesic and can produce drowsiness. Check the specific property of the drug before judging the statement.

  • Reading only the first part of Statement I and marking it true. The statement must be evaluated completely, including without producing sleep, which makes it false.

  • Confusing opium poppy as unrelated to morphine. This is incorrect because morphine and its derivatives are obtained from opium poppy. Recall the natural source of alkaloids carefully.
