Option B will be the correct option.
  Given in the question,
- Radius of the cylindrical jar = 2 inches
- Height of the jar = 5 in.
- Height of the jelly in the jar = (5 - 0.5) = 4.5 inches
Expression for the volume of a cylinder = [tex]\pi r^{2}h[/tex]
                                 = [tex]\pi (2)^2(4.5)[/tex]
                                 = [tex]18\pi[/tex]
                                 = 18(3.14)
                                 = 56.52
                                 ≈ 57 in³
   Therefore, Option B is the correct option.
 Isabelle calculated the volume of whole jar that is 63 in³ by using the same expression.
Hence, she chose Option C as the correct option.
