Based on this scenario, the mutant plant most likely germinated


A) but damage to the cotyledons prevented the seedlings' emergence from the soil.
B) but the mutated hypocotyl hook caused damage to the emerging root tip.
C) but the mutated hypocotyl hook failed to push the cotyledons above the soil.
