NumPy - Creating Arrays

Identify the error in this code snippet:

import numpy as np
lst = [[1, 2], [3, 4, 5]]
arr = np.array(lst)
print(arr.shape)

ANo error, shape is (2,)

BValueError due to uneven inner list lengths

CSyntaxError in np.array() call

DTypeError: cannot convert list to array

Step-by-Step Solution

Solution:

Step 1: Check inner list lengths
Inner lists have different lengths: 2 and 3.
Step 2: Effect on numpy array shape
Numpy creates an array of dtype=object with shape (2,), treating inner lists as objects.
Final Answer:
No error, shape is (2,) -> Option A
