Answer 2

An object considered to have only mass but no dimensions in mechanics is known as

c) Particle.

A rigid body have mass as well as height, width and volume. So, with mass it also has dimensions.

A deformable body also has mass, height, volume etc. So, it has dimensions and mass.

A particle is considered as a very small object which has mass but does not possess height, width, volume and no other dimension. So, a particle has mass but not dimension.
