  1. A 2
  2. B 1
  3. C \(\frac{1}{2}\)
  4. D \(\frac{1}{3}\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\frac{1}{3}\)

Step-by-step Solution

Detailed explanation

Intersection points: \(x^2 = |x|\). For \(x \geq 0\), \(x^2 = x \Rightarrow x(x-1) = 0 \Rightarrow x = 0, x = 1\). Due to symmetry, Area \( = 2 \int_{0}^{1} (|x| - x^2) dx \) \( = 2 \int_{0}^{1} (x - x^2) dx \) \( = 2 \left[\frac{x^2}{2} - \frac{x^3}{3}\right]_{0}^{1} \)…
