JEE Main 25 June 2022, Shift 2, Maths Q14

Question 14 of 90 in this shift, Maths question 14 of 30, Section A.

If the angle made by the tangent at the point (x0,y0)(x_0, y_0) on the curve x=12 (t+sin⁡tcos⁡t)x = 12\,(t + \sin t \cos t), y=12 (1+sin⁡t)2y = 12\,(1 + \sin t)^2, 0<t<π20 < t < \frac{\pi}{2}, with the positive xx-axis is π3\frac{\pi}{3}, then y0y_0 is equal to:
  1. (1)6(3+22)6\left(3 + 2\sqrt{2}\right)
  2. (2)3(7+43)3\left(7 + 4\sqrt{3}\right)
