Which of the following Ruby code snippets correctly uses equal? to check if two variables refer to the same object?

Aa.equal?(b)

Ba == b

Ca.equals(b)

Dequal?(a, b)

Step-by-Step Solution

Solution:

Step 1: Recall correct syntax for equal?
The method equal? is called on one object and passed another as an argument, like a.equal?(b).
Step 2: Identify incorrect options
a == b uses content equality, a.equals(b) is not a Ruby method, and equal?(a, b) is invalid syntax.
Final Answer:
a.equal?(b) -> Option A
Quick Check:
Correct equal? syntax = B [OK]

Quick Trick: Use object.equal?(other_object) syntax [OK]
