Doubt about EST Question (English for Science and Technology)

0The roof of the nasal cavity has many tiny threads called olfactory hairs dangling through it. These hairs are the dendrites of chemoreceptors called olfactory cells. Chemicals in the air, called odorant molecules, dissolve in the mucus and are absorbed by the hairs. The olfactory cells send nerve impulses to the brain which intreprets them as a smell.02br
02br
00The function of olfactory cells is to02br
02br
00a- transmit nerve impulses to the brain02br
02br
00b- dissolve the odorant molucules in the air02br
02br
00c- function as dendrites of chemoreceptors02br
02br
00d- intrepret impulses as a smell02br
02br
00The Q is I answered 'a' because I read 'The olfactory cells send nerve impulses to the brain' on the passage but it turned out to be wrong and 'c' was the correct one. But my heart says I'm still the one who is right.02br
02br
00Can someone please read and see if your answer is same as mine and whether the tutor was wrong.02br
02br
00p/s : Odorant is American spelling and Odourant is British spelling. Am I correct? 050010id7

0My answer was 'a'. Does 'c' also include the function of sending nerve impulses to the brain? If not, I'd ask your tuor whaat would happen to the creature if the cells did not peform the function of sending.02br

00As I said, my answer was A. 02br
