That would be D. Isovolumic contraction
As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases.

<span><span>These muscles that are
not striated are very smooth to the sight which is why they are also
called Smooth muscles.</span> Involuntary muscles
are not striated. Even among the striated muscles that are voluntary,
the heart which is also a muscle, is involuntary.
On the other hand the striated muscles, which
are voluntary are highly fibrous and their primary function is to move
the body voluntarily, and producing heat as a result of this muscle
action.
