• C. Sagittal plane
• D. Oblique plane

Answer: (C)

Verified step by step guidance

1. Understand the concept of anatomical planes: Anatomical planes are imaginary lines used to divide the body into sections for descriptive purposes. They help in understanding the spatial relationships of body parts.
2. Review the definitions of the listed planes: The transverse plane divides the body into superior (upper) and inferior (lower) parts, the horizontal plane is synonymous with the transverse plane, the oblique plane divides the body at an angle, and the sagittal plane divides the body into right and left parts.
3. Focus on the sagittal plane: The sagittal plane is a vertical plane that runs parallel to the longitudinal axis of the body, dividing it into right and left sections. If the division is exactly in the middle, it is called the midsagittal plane; otherwise, it is referred to as a parasagittal plane.
4. Eliminate incorrect options: The transverse and horizontal planes divide the body into upper and lower parts, which does not match the description in the problem. The oblique plane divides the body at an angle, which is also not relevant here.
5. Conclude that the sagittal plane is the correct answer: Based on the definitions and elimination of incorrect options, the sagittal plane is the anatomical plane that divides the body into right and left parts.
