Solution

The correct code snippet that creates a class with instance methods mapped to these table columns, following ORM conventions is:

class Car:
  def __init__ (self, id, make, model):
    self.id = id
    self.make = make
    self.model = model

This is because in ORM (Object-Relational Mapping), each instance of the class represents a row in the table. The id, make, and model parameters in the __init__ method correspond to the columns in the table. The self.id, self.make, and self.model are instance variables that store the values of the corresponding columns for each row (or instance of the class).
