A. the estimated population
B. that of their estimated population
C. more than the population’s estimated amount
D. more black rhinos than their population estimate
E. more than that of their population’s estimated amount

BDE, their has no referrent.

I take C over A. Sounds more clear to me.

"More" after ten times is incorrect because ten timed already means more - redundancy. Between A and B I choose A, b. it is not clear what antecedent has that.

Agree, I will also go for A
