Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Tetany is characterised by rapid spasms or wild contractions in muscles. Reason (R): The primary cause of tetany is an abnormally high level of calcium ions in the body fluid. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. ABoth Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A)
  2. BBoth Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A)
  3. CAssertion (A) is correct but Reason (R) is not correct
  4. DAssertion (A) is not correct but Reason (R) is correct

Correct answer

C. Assertion (A) is correct but Reason (R) is not correct

Step-by-step solution

Tetany is a medical condition characterised by rapid spasms or wild contractions in muscles. This makes Assertion (A) correct. The primary cause of tetany is an abnormally low level of calcium ions (hypocalcemia) in the body fluid, not a high level. This makes Reason (R) incorrect. Therefore, Assertion (A) is correct but Reason (R) is not correct.
