DTo confuse other programmers reading the code
Step-by-Step Solution
Solution:

  1. Step 1: Understand the purpose of standard library modules

    Standard library modules contain pre-written, tested code for common tasks like math operations or random number generation.

  2. Step 2: Identify the benefit of using these modules

    Using these modules saves time and reduces errors because you don't have to write and test the code yourself.

  3. Final Answer:

    To reuse tested code and avoid writing common functions from scratch -> Option C

  4. Quick Check:

    Standard library modules help reuse code = B [OK]
Quick Trick: Standard modules save time by reusing tested code [OK]
