(A) star-nosed moles navigate their tunnels using highly sensitive Eimer’s organs and forage for worms and insects, feeding quickly enough
"it" in the non underlined portion has no referent. Also it conveys a weird meaning; navigating and foraging helps moles somehow to feed quickly
(B) star-nosed moles navigate their tunnels using highly sensitive Eimer’s organs, they forage for worms and insects, and with such quick feedings
"it" in the non underlined portion has no referent. Also we have a comma splice [star nosed moles navigate..] an IC separated by a comma from another IC [they forage for worms and insects]. Lastly "and with such quick feedings..." breaks the parallelism
(C) star-nosed moles use highly sensitive Eimer’s organs to navigate their tunnels, forage for worms and insects, and feed so quickly
"it" in the non underlined portion has no referent.
(D) the star-nosed mole navigates its tunnels using its highly sensitive Eimer’s organs, forages for worms and insects and it feeds quickly enough
Parallelism is violated; navigates (verb) + forages(verb) + it feeds (a clause)
(E) the star-nosed mole navigates its tunnels using its highly sensitive Eimer’s organs, foraging for worms and insects and feeding so quickly
CorrectTBH, ı don't like this option either Meaning is off IMO. mole navigates tunnels by foraging and by feeding so quickly? No ı don't think so...
Also In option A, B, D and E "navigate tunnels using its highly sensitive..." is off. Though one can understand the meaning, "navigate tunnels by using..."would be much better and clearer, otherwise it absurdly seems like a restrictive participial modifying the tunnels...
