Explanation:
Assertion:
The orthocentre of a given triangle is coincident with the incentre of the pedal triangle of the given triangle.
Reason:
Pedal triangle is the ex-central triangle of the given triangle.
The assertion is true because the orthocentre of a triangle is the point of intersection of its altitudes, and the incentre of a triangle is the point of intersection of its angle bisectors. The pedal triangle is constructed by drawing perpendiculars from the vertices of the original triangle to the sides of a reference triangle. The incentre of the pedal triangle coincides with the orthocentre of the original triangle.
The reason is false because the pedal triangle is not the ex-central triangle of the given triangle. The ex-central triangle is constructed by drawing lines parallel to the sides of the given triangle through the excenters.
Therefore, the correct answer is option 'C' - Assertion is true but Reason is false.

A pedal triangle is obtained by projecting a point onto the sides of a triangle. More specifically, consider a triangle ABC, and a point P that is not one of the vertices A, B, C. Drop perpendiculars from P to the three sides of the triangle. The same is done for obtaining the orthocentre. Thus, orthocentre of the original triangle and the incentre of the pedal triangle and are coincident.
