NumPy - Array Operations

Why might in-place operations sometimes fail or raise errors in numpy?

ABecause numpy does not support in-place operations

BWhen the array is read-only or has incompatible data types

CDue to lack of internet connection

DBecause in-place operations always create copies

Step-by-Step Solution

Solution:

Step 1: Identify conditions blocking in-place operations
Arrays that are read-only or have data types that cannot be safely cast cause errors.
Step 2: Eliminate incorrect options
In-place ops do not create copies; internet connection is irrelevant; numpy supports in-place ops.
Final Answer:
When the array is read-only or has incompatible data types -> Option B
Quick Check:
Read-only or type mismatch blocks in-place ops [OK]

Quick Trick: In-place fails if array is read-only or types mismatch [OK]
