Explanation Explanation for the correct answer: Option (b) is given that vision is affected. The symptoms associated with stroke include headache, numbness of body parts like face, arm, or leg, confusion, trouble in walking, and vision problems in one or both eyes. A stroke, which occludes or blocks a posterior cerebral artery, which supplies blood to the posterior part of the brain, affects the brain. This, in turn, causes damage to the vision. Hence, option (b) is correct. Explanation for incorrect answers: Option (a) is given that hearing is affected. When the pathway of a posterior cerebral artery is blocked during a stroke, the blood is not supplied to the posterior brain. Hearing problems are not caused due to damage to the posterior side of the brain because the auditory cortex, which controls hearing, is supplied mainly by the middle cerebral artery...

Summary Introduction

Introduction:

Stroke is a medical condition that occurs due to either interrupted or reduced supply of blood to the brain. As a result, the brain does not receive the sufficient amount of oxygen and nutrients. This further causes the brain cells to die, which results in brain cell death. The posterior cerebral artery is one of the two vertebral arteries.
