Figure 3 shows a logic circuit diagram with three inputs, labeled X, Y, and Z, and three logic gates, labeled Gate 1, Gate 2, and Gate 3.

A logic circuit diagram with three inputs: X, Y, and Z. Input X connects to the input of Gate 1. Gate 1 is a triangular symbol with a small circle at its tip. The output of Gate 1 and input Y are connected to the inputs of Gate 2. Gate 2 is a D-shaped symbol with a straight input boundary and a rounded output front. The output of Gate 2 and input Z are connected to the inputs of Gate 3. Gate 3 has a curved input boundary and a pointed nose at its output. The output of Gate 3 connects to the circuit's final output.

State the name of the logic gate used at Gate 2 in Figure 3.
