Answer:
I love this car, especially its color.
Explanation:
The use of pronouns in any sentence is to avoid the repetition of the same noun again and again. This shortens the sentence and also makes the sentence more refined and easier to understand. For the above provided sentence, the correct pronoun will be "ITS" as it represents the car or it denotes the possessive form of the car. And a car is non living, neuter gender. It is wrong to use "it's" as it is the short form of 'it is' which is not applicable for the car. "Its" is a possessive form whereas "it's" is the contracted form of it is.
