Answer:
C. John Hancock.
Step-by-step explanation:
An allusion is a figurative speech when a reference is made to something that is unrelated. In other words, an allusion is the use of one object to refer to something that is not related to each other.
In the given passage, the allusion made is in the use of the term "John Hancock". This is in reference to President John Hancock, who was famous for his big and bold signature when signing the Declaration of Independence. Since then, the term "John Hancock or Hancock" is used to refer to one's act of signing signatures.
Thus, the correct answer is option C.
