In which of the following life cycle stages is enterobiasis transmitted? (AIIMS May 2012)
The egg stage is the stage transmitted from person to person.
A larval form (A) is found inside the egg but does not escape to initiate infection until the egg is ingested.
Adult forms (C) live in the intestine but are not the stage directly responsible for transmission of the infection.
Cyst (D) and oocyst (D) stages are not a part of the life cycle of E. vermicularis.
