=IF(A3>10,B3*C3,IF(A<100,B3*D3,0)) is known as a(n):

IF statement.
nested IF.
enclosed IF.
multiple criteria IF.

multiple criteria IF

The correct answer is "nested IF."

A nested IF statement is a formula in Microsoft Excel that contains multiple IF functions nested inside each other. In the given formula, we can see that there are multiple IF functions being used to check different conditions.

The first condition being checked is A3>10. If this condition is true, then the formula will return B3*C3. If the condition is false, it moves on to the second IF function.

The second condition being checked is A<100. If this condition is true, then the formula will return B3*D3. If the second condition is false, the formula will return 0.

Since there are multiple IF functions nested inside each other, this formula is called a nested IF statement.
