Steps are given to locate the directrix of hyperbola when axis and foci are given. Arrange the steps.i. Draw a line joining A with the other Focus F.ii. Draw the bisector of angle FAF1, cutting the axis at a point B.iii. Perpendicular to axis at B gives directrix.iv. From the first focus F1 draw a perpendicular to touch hyperbola at A.

• A. i, ii, iii, iv
• B. ii, iv, i, iii
• C. iii, iv, i, ii
• D. iv, i, ii, iii
