(B) The life cycle of $Ascaris$ $lumbricoides$ involves several larval stages.After the ingestion of embryonated eggs containing the $second$ stage larvae,these larvae hatch in the intestine.The $second$ stage larva is considered the infective stage for humans.However,in many biological contexts,the $third$ stage larva is also recognized as a developmental stage that occurs after migration through the lungs and re-entry into the digestive tract.Therefore,the $second$ and $third$ larval stages are commonly associated with the infective process in the host.
