Answer

Correct answer:C

Step-by-step solution

Standard Method

Given: Two statements about morphine are to be evaluated.

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

Statement I: Morphine is a narcotic analgesic, but it is known to induce sleep and drowsiness. Therefore, the statement "It helps in relieving pain without producing sleep" is false.

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

Conclusion: Statement I is false, but Statement II is true. Therefore, the correct option is C.

Statement-wise Analysis

Given: Two statements related to morphine.

Find: The correct combination of true and false statements.

  1. Morphine is a narcotic analgesic and is used for pain relief.
  2. However, morphine also causes drowsiness and may induce sleep.
  3. Hence, Statement I is false.
  4. Morphine and its derivatives are obtained from the opium poppy.
  5. Hence, Statement II is true.

Conclusion: The correct choice is Statement I is false, but Statement II is true, which corresponds to option C.

Common mistakes

  • Assuming that all analgesics relieve pain without causing sleep is incorrect because narcotic analgesics like morphine can cause drowsiness. Check the specific property of the compound before deciding the statement.

  • Confusing the option number from a mismatched the solution with the actual statement combination can lead to a wrong answer. Always map the statement combination to the listed options carefully.

  • Thinking that morphine is synthetic and not obtained from a natural source is incorrect. Morphine and its derivatives are obtained from the opium poppy, so Statement II must be treated as true.
