What is a **two-dimensional array**?

In the general case, two-dimensional arrays are called **matrices**: such mathematical structures that consist of **rows** and **columns**. If it will be easier for you, then you can represent the matrix as a table.
To create a 2-D array, pass list of lists as the parameter of `np.array()` function (nested lists must be the same length).

import numpy as np
# Creating array
arr = np.array([[5.2, 3.0, 4.5], [9.1, 0.1, 0.3]])
# Displaying array
print(arr)

Select all options with the INcorrect code of creating 2-D arrays.
