In ΔPQR let d1, d2, d3 be the altitudes on QR, RP and PQ respectively.


⇒ 
⇒ d1, d2, d3  are  in H.P. (As given that sin P,  sin Q,  sin R  are in A.P.)

Explanation:

Altitudes in Harmonic Progression:
- In a triangle, the altitudes are in Harmonic Progression if the sines of the angles are in Arithmetic Progression.
- So, if sin P, sin Q, sin R are in A.P., then the altitudes are in H.P.

Harmonic Progression:
- In mathematics, a harmonic progression is a sequence of numbers in which the reciprocals of the terms are in Arithmetic Progression.
- In a triangle, the lengths of the altitudes are in Harmonic Progression if the sines of the angles are in Arithmetic Progression.

Relation between Sines and Altitudes:
- The lengths of the altitudes in a triangle are inversely proportional to the sines of the corresponding angles.
- This means that if sin P, sin Q, sin R are in A.P., then the reciprocals of the sines (1/sin P, 1/sin Q, 1/sin R) are in A.P.
- Therefore, the lengths of the altitudes are in H.P.

Conclusion:
- In a triangle PQR, if sin P, sin Q, sin R are in A.P., then the altitudes of the triangle are in Harmonic Progression (H.P).
- Hence, option 'B' - the altitudes are in H.P. - is the correct answer.
