It should be something that comes from your heart, something you're emotionally attached too or something that you find passion about.
I believe the correct answer is C. suite.
Suite is a set of instrumental or orchestral pieces
which are performed in succession. George Frideric Handel's “Water Music” is an
example of a suite and it’s often published in three suites: Suite in F major
(HWV 348), Suite in D major (HWV 349) and Suite in G major (HWV 350).
