What type of poem is this?

"And in fresh numbers number all your graces,
The age to come would say 'This poet lies;
Such heavenly touches ne'er touch'd earthly faces.
So should my papers yellow'd with their age
Be scorn'd like old men of less truth than tongue,
And your true rights be term'd a poet's rage
And stretched metre of an antique song:
But were some child of yours alive that time,
You should live twice; in it and in my rhyme."

A. Sestina
B. Ode
C. Sonnet
D. Haiku
