What is the primary benefit of using NumPy arrays for numerical computation instead of Python lists or tuples?

What is the purpose of the dtype argument when creating a NumPy array using the np.array() function?

To set the dimensions of the resulting NumPy array.
To explicitly specify the data type of the elements in the resulting NumPy array.
To control the memory usage of the resulting NumPy array.
To determine the shape of the resulting NumPy array.
