Final answer:
The word 'void' best matches with 'a) emptiness', describing the absence or lack of content, closely associating with the concept of a void. So, the best answer is a, emptiness
Step-by-step explanation
The question asks which of the following words matches the word "void": a) emptiness, b) vacantness, c) vacuum, d) blankness.
The word "void" is often used to describe an absence or a space that is unoccupied or doesn't contain anything.
All four options given can be related to the concept of a void, but the best match is a) emptiness.
Emptiness implies a lack of content or the presence of nothing, which is what "void" is mainly used to convey.
For example, after moving out of an apartment, it may be described as void of furniture, or an empty room could be referred to as a void space.
So, the best answer is a, emptiness.
