NumPy - Aggregation Functions

What is wrong with this code snippet?

import numpy as np
arr = np.array([1, 2, 3])
result = np.prod(arr, axis=3)
print(result)

Anp.prod() does not accept an axis argument

BAxis 3 is out of bounds for a 1D array

CThe array must be 2D to use np.prod()

DThe print statement is missing parentheses

Step-by-Step Solution

Solution:

Step 1: Check array dimensions
The array arr is 1D with shape (3,).
Step 2: Validate axis parameter
Axis values must be within the array's dimensions. For 1D arrays, valid axis values are 0 or None.
Step 3: Identify error
Using axis=3 is invalid and causes an IndexError.
Final Answer:
Axis 3 is out of bounds for a 1D array -> Option B
Quick Check:
Axis must be less than array.ndim [OK]

Quick Trick: Axis must be less than array dimensions [OK]
