The correct answer will be a slide of striated muscle fibers.
- Skeletal muscles show striations and they are long and cylindrical.
- They have light and dark bands which help in contraction.
- The light band is called I-band /isotropic band and Dark band is called
A-band/anisotropic band.
- Dark band is made up of myosin filament while Light band is made up of actin filament.

Option A is correct
A slide of striated muscle fibre will be the proper response.
- Striations may be seen on skeletal muscles, which are long and cylindrical.
- They are made up of bright and dark bands that aid in contraction.
- The bright band is referred to as the I-band or isotropic band, whereas the dark band is referred to as the
- Anisotropic band (A-band).
- Myosin filaments make up the dark band, whereas actin filaments make up the light band.
