b.

REASON :

In fig. 1 there is front view of a triangle pyramid.

It can be seen that it has 3 triangular faces and one triangle as its base.

In fig. 2 there is top view of the triangular pyramid where it can be seen that a triangular portion is obtained when it is sliced perpendicularly to the base.

HOPE IT IS USEFUL

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
