Final answer:
The plane that bisects the body into front and back halves is the frontal or coronal plane. Therefore, the correct answer is both a) Frontal plane and d) Coronal plane, as they are synonymous terms.
Step-by-step explanation:
The plane of motion that bisects the body into front and back halves is known as the frontal plane or coronal plane. This plane divides the body into anterior (front) and posterior (back) portions. The other planes mentioned are the sagittal plane, which divides the body into right and left portions, and the transverse plane, which divides the body horizontally into upper and lower portions. Thus, the correct answer to the question in reference to which plane bisects the body into front and back halves is:
b) Sagittal plane bisects the body into front and back halves.
Incorrect, the sagittal plane divides the body into right and left sides.
a) Frontal plane bisects the body into front and back halves.
Correct, the frontal plane bisects the body into front and back halves.
c) Transverse plane bisects the body into front and back halves.
Incorrect, the transverse plane divides the body into upper and lower portions.
d) Coronal plane bisects the body into front and back halves.
Correct, the coronal plane also refers to the frontal plane, which bisects the body into the anterior and posterior.
