Which of the following is the correct way to define the + operator method in a Ruby class?

Adef +(other); ... end

Bdef plus(other); ... end

Cdef add(other); ... end

Ddef operator_plus(other); ... end

Step-by-Step Solution

Solution:

Step 1: Recall operator method syntax
In Ruby, operators like + are defined by naming the method exactly as the operator symbol.
Step 2: Match method name to operator
So to define +, you write def +(other), not other names like plus or add.
Final Answer:
def +(other); ... end -> Option A
Quick Check:
Operator method name = operator symbol [OK]
