Given two straight lines \( A B \) and \( A C \) whose equations are \( 3 x+4 y=5 \) and \( 4 x-3 y=15 \) respectively. Then the possible
\( \mathrm{P} \) equation of line \( B C \) through \( (1,2) \), such that \( \triangle A B C \) is isosceles,

W is \( L_{1}=0 \) or \( L_{2}=0 \), then answer the following questions
A straight line through \( P(2, c+f-1) \), inclined at an angle of \( 60^{\circ} \) with positive \( Y \)-axis in clockwise direction. The co-ordinates of one of the points on it at a distance \( (c+f) \) units from point \( P \) is (c, fobtained from previous question)
(a) \( (2+2 \sqrt{3}, 5) \)
(b) \( (3+2 \sqrt{3}, 3) \)
(c) \( (2+3 \sqrt{2}, 4) \)
(d) \( (2+3 \sqrt{2}, 3) \)
