Read the poem given below and answer questions

I know a funny little man,
As quiet as a mouse, (2)
Who does the mischief that is done
In everybody’s house!
There’s no one ever sees his face,
And yet we all agree
That every plate we break was cracked
  By Mr. Nobody.

’Tis he who always tears out books,
  Who leaves the door ajar,
He pulls the buttons from our shirts,
  And scatters pins afar;
That squeaking door will always squeak,
  For prithee, don’t you see,
We leave the oiling to be done
  By Mr. Nobody.
He puts damp wood upon the fire
  That kettles cannot boil;
His are the feet that bring in mud,
  And all the carpets soil.
The papers always are mislaid;
  Who had them last, but he?
There’s no one tosses them about
  But Mr. Nobody.
The finger marks upon the door
  By none of us are made;
We never leave the blinds unclosed,
  To let the curtains fade.
The ink we never spill; the boots
  That lying round you see
Are not our boots,—they all belong
  To Mr. Nobody.

What is the figure of speech used in line 2 ?

Simile

The correct answer is OPTION 1 - Simile

The second line of the poem states:
"As quiet as a mouse."

This is a simile because it compares the "funny little man" (Mr. Nobody) to a mouse, using the word "as" to make the comparison. Similes are used to describe something by directly comparing it to another thing with the words "like" or "as."
