D

Explanation

H = mc

HP = HQ, P = 2q,

mP = \(\frac{1}{2}\)mQ

HP = mQCPP, also HQ = mQCQQ

Since HP = HQ

mPcPP = mQcPq

Putting in the conditions

\(\frac{1}{2}\)mQ \(\times\) cP \(\times\) 2Q = mQ \(\times\) Q \(\times\) cQ

cP = cQ

\(\frac{C_p}{C_Q}\)= \(\frac{1}{1}\)

= 1:1


Correct option: C
