dilation of the pupil of the eye
B
excessive constriction of the pupil of the eye
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Dilated pupils (mydriasis) are when the black center of your eyes are larger than normal. The condition may be caused by dilating eye drops from an eye exam, the side effects from a drug/medication or traumatic injury.

Detailed explanation-2: -Mydriasis is the dilation of the pupil, usually having a non-physiological cause, or sometimes a physiological pupillary response.

Detailed explanation-3: -Potential causes of unusual mydriasis include injury to the muscles or nerves of the eye, traumatic brain injury, increased levels of oxytocin, and side effects of certain recreational drugs or prescribed medications. Additionally, there are also certain conditions that may result in mydriasis.

Detailed explanation-4: -Sometimes pupils will dilate for a reason unrelated to the levels of light in the environment. They may stay enlarged even in bright environments. Doctors refer to this condition as mydriasis. The opposite of mydriasis is when pupils constrict and get smaller. This is called miosis.

Detailed explanation-5: -Dilating your pupil lets more light into your eye-just like opening a door lets light into a dark room. Dilation helps your eye doctor check for many common eye problems, including diabetic retinopathy, glaucoma, and age-related macular degeneration (AMD).
