Answer:
The correct answer will be option A - A-band.
Explanation:
The sarcomere is the repeating unit of a myofibril which extends between two z-lines. Under a microscope, a sarcomere can be divided into A- band which is composed of thick myosin only and I-band which consists of thin filament that is actin only.
When a muscle contract then actin and myosin comes in overlapping position due to which I-band shortens and between two z-lines and overlapped structure of thin actin filaments over thick myosin filaments (A-band) is seen.
Therefore, only A-band is seen between two z-lines in a contracted muscle thus, option A is the correct answer.
I believe that’s true.

Explanation:
Brain-imaging technique- <u><em>this comprises of different techniques for analyzing the brain's activities as well as structure, function and other problems.</em></u>
There are many brain-imaging techniques such as <u>Positron Emission Tomography or PET,</u> which traces the part of the brain that is activated during specific tasks as well as the localization of brain activity in response to a specific stimulus. These areas are seen with high radioactivity.
Patterns of blood flow in the brain can be detected by using <u>MRI (Magnetic Resonance Imaging) test.</u> There is an increase in blood flow to areas in the brain with high activity level.
With the explanation given, it shows that letter c is the only choice that the brain-imaging techniques cannot determine.
