Correct Answer: Flourish

Solution : The correct choice is the second option.

Flourish means to grow or develop in a healthy or vigorous way, which aligns with the idea of plenty or abundance.

The meanings of the other options are as follows:

• Increase: While "increase" is related to growth in quantity or size, it is not a direct synonym for "abound."

• Succeed: "Succeed" refers to achieving a goal or reaching a desired outcome.

• Adequate: It means sufficient or satisfactory.
