Answer:
Option B i.e. Accommodation.
Explanation:
The right option for this is option B i.e. "Accommodation".
This is a very important property of human eye. A person can easily see something situated quite near or quite far to him/her by adjusting the focal length of his eye. He accommodates his eye's focal length and hence it is called "accommodation" in Physics.
On the other hand, the other options are conditions when one cant see things situated nearby, or far off, etc.
