Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Break the word into fecund (capacity to bear young) plus super; it points to extra fertilizing events within one cycle, not across cycles.
Step 2: Superfecundation means two ova of the same cycle are fertilized by sperm deposited in distinct acts of intercourse, which can even yield twins fathered by two different men.
Step 3: Eliminating the rest: a single intercourse (A) is too narrow, splitting of one fertilized egg (C) is monozygotic twinning, and fertilizing a fresh ovum after an existing implantation (D) is superfetation. Only option B fits.
\[\boxed{\text{Two or more ova in different intercourses in the same menstrual cycle}}\]
