Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The eccentricity of a hyperbola is always greater than 1. Reason (R): For a hyperbola, \( c > a \) since \( c^2 = a^2 + b^2 \) and \( b^2 > 0 \). In the light of the above statements, choose the correct answer from the options given below:

  1. A
    Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. B
    Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. C
    (A) is true but (R) is false.
  4. D
    (A) is false but (R) is true.

Correct answer · Option A

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation

Since \( c > a \), eccentricity \( e = \frac{c}{a} > 1 \). Thus, both Assertion and Reason are true, and Reason correctly explains Assertion.
