Correct option is C
The question states that individuals in a particular population under stress produce smaller offspring. This observation suggests a possible association between stress and the size of offspring, but it does not confirm a causal relationship.
That is why option (c) — "Stress may be linked to offspring size" — is the most cautious and scientifically appropriate conclusion from the given data. This avoids overinterpreting the results by not assuming directionality or causation.
Options like (a) and (d) assume more than what is directly stated. For instance:
(a) assumes that number of offspring is not affected — but the question gives no information about offspring number.
(d) assumes direct causality, which is not proven by a single observation.
(b) introduces the notion of preference, which implies cognitive intent — again, not supported by the evidence.
Therefore, Option (c) best reflects a scientific, evidence-based interpretation.
Hence, the correct answer is (c) Stress may be linked to offspring size.
