"The volume of blood remaining in the ventricle after contraction" is the correct answer

"yo" is wrong.
Systole is the contraction phase of the ventricular cycle. At the end of systole, the heart has emptied itself of all the blood that it will eject. What remains is not zero blood, but some fraction of it's original volume. This is the end systolic volume.
"The volume of blood remaining in the ventricle after contraction."

End systolic volume is the blood left in the ventricle after contraction (systole). The fourth answer.
This is subtracted from end diastoplic volume (EDV) to generate stroke volume, which when divided by EDV yields ejection fraction.
