NumPy - Creating Arrays

import numpy as np
arr = np.ones((2, 2), dtype=float)
print(arr)

A[[1 1] [1 1]]

B[[1. 1.] [1. 1.]]

C[[1 1 1] [1 1 1]]

D[[0. 0.] [0. 0.]]

Step-by-Step Solution

Solution:

Step 1: Understand the shape and dtype
The shape is (2, 2), so the array has 2 rows and 2 columns. The dtype is float, so elements are floats.
Step 2: Predict the printed output
Each element is 1.0, printed as 1. with a decimal point. So the output is a 2x2 array of 1.0 values.
Final Answer:
[[1. 1.] [1. 1.]] -> Option B
Quick Check:
Shape (2,2) and float type means 1.0 values [OK]

Quick Trick: Float dtype shows decimal points in output [OK]
