SciPy - Integration with Scientific Ecosystem

Find the bug in this code:

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

Anp.dot cannot be used with integers

Bnp.dot requires two arrays, not an array and a scalar

Cnp.array is missing dtype specification

DCode runs correctly and prints 6

Step-by-Step Solution

Solution:

Step 1: Check np.dot parameters
np.dot expects two arrays or matrices, not an array and a scalar.
Step 2: Identify correct usage
To multiply array by scalar, use * operator instead of np.dot.
Final Answer:
np.dot requires two arrays, not an array and a scalar -> Option B
Quick Check:
np.dot needs two arrays [OK]

Quick Trick: Use * for scalar multiply, dot() for array-array multiply [OK]
