Comprehension
A circle \( C \) whose radius is 1 unit, touches the \( x \)-axis at point \( A \). The centre \( Q \) of \( C \) lies in first quadrant. The tangent from origin \( O \) to the circle touches it at \( T \) and a point \( P \) lies on it such that \( \triangle O A P \) is a right angled triangle at \( A \) and its perimeter is 8 units.
The length of \( Q P \) is
(a) \( 1 / 2 \)
(b) \( 4 / 3 \)
(c) \( 5 / 3 \)
(d) \( 2 / 3 \)
