The correct answer is   .

Please Note:

A fraction represents a part of a whole.

For instance:

• each part of a shape, when divided into two equal parts, is called a half.
• each part of a shape, when divided into three equal parts, is called a third.
• each part of a shape, when divided into four equal parts, is called a fourth.
• each part of a shape, when divided into five equal parts, is called a fifth.

Solution:

We consider all the fraction models one by one in order to identify the fraction showing three-fifths.

• We consider the first fraction model.
  
  The given fraction model shows five equal parts.
  The shaded part of the fraction model shows a one-fifth.
  One-fifth means one of five equal parts.
• Looking at the second fraction model.
  
  The given fraction model shows five equal parts.
  The shaded part of the fraction model shows three-fifths.
  Three-fifths means three of five equal parts.

Therefore, the fraction model,    shows three-fifths.
