**(d)**

(1) Direction ratio of the joining the points (1, 2, 5) and (4, 3, 2) is (3, 1, ) and direction ratios of the joining the points (5, 1, 1) and (8, 2, ) is (3, 1, 3)

These are parallel

(2) It is true

(3) Direction ratios of the plane are (1, , 1) and direction ratios of the line are (1, 2, 3). If they are parallel, then
