Consider the lines l1:x−10=y−11=2−z1l_1: \frac{x-1}{0} = \frac{y-1}{1} = \frac{2-z}{1} and l2:x2=y0=2z−14l_2: \frac{x}{2} = \frac{y}{0} = \frac{2z-1}{4}, then which of the following are correct?

(A) Direction Ratio's of l1=<0,1,1>l_1 = <0, 1, 1>

(B) Direction Ratio's of l2=<2,0,2>l_2 = <2, 0, 2>

(C) Angle between l1l_1 and l2=l_2 = π3\frac{\pi}{3}

(D) Angle between l1l_1 and l2=l_2 = 2π3\frac{2\pi}{3}
