Given that the marginal revenue of the 100th unit of output is $10 and the marginal cost is $11. 
For profit maximization, the firm should produce units where marginal revenue (MR) is equal to marginal cost (MC).

Since MR < MC for the 100th unit, producing the 100th unit would result in a decrease in profits. 
Therefore, the firm's profit-maximizing level of output is less than 100 units.

Option A is incorrect because producing the 100th unit reduces profits by $1. 
Option B is incorrect because the average total cost is not given and cannot be concluded from the given information. 
Option D is incorrect because the marginal profit of the 110th unit cannot be determined from the given information.
