Correct Answer: large

Solution : The correct choice is the fourth option .

The appropriate option is large , which functions as an adjective describing the size or quantity of the number of textile traders providing support.

The meanings of the other options are as follows:

• Larging is not a correct word in this context.
• Largest refers to the superlative form of large, indicating the greatest in size or amount. However, in this sentence, the intention is to describe a significant or considerable number, not necessarily the greatest .
• Largely means mainly or mostly, but it doesn't fit well in this context because it describes the manner or way something is done, not the quantity or size of the traders.

Therefore, the complete sentence is: We are getting support from a large number of textile traders.
