Final answer:
The frontal plane, or coronal plane, divides the body vertically into anterior and posterior portions, not horizontally into upper and lower portions or into equal or unequal left and right portions.
so the correct answer is Option A
Step-by-step explanation:
The frontal plane, also known as the coronal plane, is an anatomical boundary that is perpendicular to the body. It divides the body into anterior (front) and posterior (rear) portions. When considering how a frontal plane cuts the body, the correct answer is a) Vertically into anterior and posterior portions. This is distinct from the sagittal plane, which cuts the body into right and left portions, and the transverse plane, which cuts the body horizontally into upper and lower portions.
the correct answer is Option A
