Answer:
<em>"The doctor will give her a series of tests to see how well she can think"</em>
Explanation:
"Cognitive" relates to cognition, the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses—basically, all the super-important brain stuff.
The first option relating to the eyes would be something more suited towards an ophthalmologist (fancy word for 'eye doctor'). The third matches more towards cardiac and respiratory problems, heart things and lung/breathing stuff respectively. The final tests for your reflexes and muscles.
Using the process of elimination (and some funky words), the awnser becomes clear: the second choice (or "B.") is most likely true.
Hope this helps! Brainliest appreciated.
