Who among the following attached himself to the Earl of Nottingham’s theatrical company?

The correct answer is Christopher Marlowe.

In Elizabethan England, theatrical companies were organized under the patronage of noblemen. The Earl of Nottingham’s Men (also known as the Admiral's Men because Charles Howard, the Lord Howard of Effingham, held the office of Lord High Admiral and later became the Earl of Nottingham) was one of the most prominent playing companies of the era.
Christopher Marlowe was closely associated with this company. Most of his famous plays, including Tamburlaine the Great, The Jew of Malta, and Doctor Faustus, were written for and performed by the Admiral's Men (the Earl of Nottingham’s company), primarily starring their leading actor, Edward Alleyn.
