Best answer
Correct option is (b) voxel

Explanation: Voxel stands for the volumetric pixel. MRI is unique in a way that it can image segments of the organ from different angles with various slice selections. These slice selections help choose which layer of the organ will be imaged and the smallest unit of this image is called a voxel. Since MRI can produce 3D scans, the image is volumetric in nature and thus, volumetric pixel or voxel is used.
