The question wants to show a contrast - decrease, but deaths continued.

(C) Although life expectancy for children improved after the Colonial period, during which the mortality rate was 50 percent, .....correct in many ways -
1) Incorrect usage of "period's" is rectified
2) Colonial period is correctly defined/ explained by using "during which" ie dependant clause is correctly "defining" the Colonial period.
3) Contrast in sentence is maintained by using Although

IMO C

The main problem is the unidiomatic branding of the mortality rate as the 50% mortality rate, as though it were a kind of milestone or reference rate.

(A) After ‘the Colonial period’s 50 percent mortality rate’, life expectancy improved for children, but …. unidiomatic
(B) Even though children’s life expectancy, which improved over ‘the Colonial period’s 50 percent mortality rate,’ ---- unidiomatic; in addition, the subordinate clause is a fragment
(C) Although life expectancy for children improved after the Colonial period, during which the mortality rate was 50 percent, …. Avoids the idiom error; best choice
(D) While there was an improvement in life expectancy for children after ‘the 50 percent mortality rate of the Colonial period’, still ……unidiomatic
(E) Despite children’s ‘life expectancy improvement’ from ‘the Colonial period’s 50 percent mortality rate’, …unidiomatic

C seems the correct answer. this question tests idioms, which is a weak link for me.

Between B and C,

usage of children’s life expectancy with Colonial period’s 50 percent mortality rate is problematic.

C life expectancy is correctly compared with mortality rate here. Hence a better choice.

C.
