Ruby - String Operations

The following Ruby code is intended to convert a string name to lowercase and remove spaces at the start and end. What is wrong?

name = "  RubyLang  "
name.downcase.strip

AThe method <code>strip</code> does not exist

BThe methods are called in the wrong order

CThe result is not saved or printed

DThe string should be converted to uppercase instead

Step-by-Step Solution

Solution:

Step 1: Check method calls and order
Both downcase and strip are valid methods and can be chained in any order.
Step 2: Check if result is used
The code calls methods but does not save or print the result, so the original string remains unchanged.
Final Answer:
The result is not saved or printed -> Option C
Quick Check:
Method calls without assignment or output do nothing visible [OK]

Quick Trick: Always save or print method results to see changes [OK]
