Which of the d orbitals lies in the xy-plane ?

Options

A. `d_(xz)`
B. `d_(xy)`
C. `d_(x^(2)-y^(2)`
D. `d_(xy) and d_(x^(2) - y^(2)`

Explanation

To determine which of the d orbitals lies in the xy-plane, we need to analyze the shapes and orientations of the five d orbitals: d_xy, d_xz, d_yz, d_x²-y², and d_z².

### Step-by-Step Solution:

1. **Identify the d Orbitals**:
The five d orbitals are:
- d_xy
- d_xz
