A Correct answer
Explanation

This uses the 'anticipatory it' structure where 'it' serves as the grammatical subject, while the real logical subject is the infinitive phrase 'to learn how to play the piano'. 'That' and 'this' are demonstrative pronouns and cannot serve this anticipatory function in this context.
