问题 This egg mortality was not due to parental ageing was indicated by the similar trends taking place in pods laid by old or young adults.

选项 A、For this egg mortality was not
B、Why this egg mortality was not
C、That this egg mortality was not
D、Which this egg mortality was not

答案 C

解析句中谓语动词为was indicated…，画线部分是主谓结构，导致主句没有主语成分。因此在画线部分之前添加that，主语从句位于句首，that不能省略，C正确。
