To evaluate the expression, we need to enter it into the calculator as: sin(11e^(-2)x) + cos(5x) + tan(4x). Then, we can graph the function and observe the y-values at different x-values to find the maximum. The maximum y-value appears to be around y=2.7, which corresponds to a maximum point at x=2.5. To verify this, we can use the calculator's maximum function by pressing "2nd", "Calculate", "Maximum", and then selecting the interval [0, 5] (or any other suitable interval). The calculator confirms that the maximum value is approximately 2.7 at x=2.5. Choice B matches this answer.
