Correct Answer: Massive

Solution : The correct option is the third option.

Explanation : Bulky refers to something that is large and takes up a lot of space. Similarly, "massive" conveys the idea of being large, substantial, or having considerable size. In the context of synonyms, "massive" is appropriate to describe something bulky.

The meaning of the other options is as follows:

• Airy : This term refers to something light and spacious.
• Soft : This term refers to the texture or firmness, not the size or volume.
• Scanty : This term means small or insufficient, which is the opposite of bulky.
