BCalling instance method on class

Cstart_engine method undefined

DSyntax error in method definition

Step-by-Step Solution

Solution:

Step 1: Analyze method calls
start and start_engine are instance methods, but Car.start calls start on the class.
Step 2: Understand method call context
Instance methods cannot be called directly on the class; this causes a NoMethodError.
Final Answer:
Calling instance method on class -> Option B
Quick Check:
Instance methods need an instance to be called [OK]

Quick Trick: Instance methods require an object, not class name [OK]
