​Which of the following pairs of traits is most likely in a species when maternal investment is very high?​
Question

Which of the following pairs of traits is most likely in a species when maternal investment is very high?

A.

Multiple reproductive events and high maternal mortality

B.

Slow developmental rates and low maternal fecundity

C.

Few reproductive events and low maternal fecundity

D.

Few reproductive events and high maternal mortality

Correct option is C

Explanation-

Species with high maternal investment generally:
   (i)  Produce few offspring (low fecundity)
   (ii) Reproduce infrequently (few reproductive events)
   (iii) Focus more on offspring survival than quantity
Follow a K-selection strategy (stable environments, quality > quantity)

Incorrect Options-
Option a: Multiple reproductive events and  high maternal mortality
High maternal mortality contradicts high investment (it’s not sustainable). Multiple events is more aligned with low investment, r-selected species
Option b: Slow development and low maternal fecundity
Though slow development fits, development rate is not the key trait being asked. Maternal fecundity being low is good, but this misses the reproductive event part.
Option d: Few reproductive events and high maternal mortality
High maternal mortality still contradicts long-term parental investment needed for high maternal care.

Correct answer - Option c - ​Few reproductive events and low maternal fecundity
