Answer:
The correct option is B.
Step-by-step explanation:
In a right angled triangle
[tex]\sin \theta=\frac{perpendicular}{hypotenuse}=\frac{opposite}{hypotenuse}[/tex]
In the given triangle DEF, the opposite sides of angle E is DF=6 units and hypotenuse EF=10 units.
The sine ratio of angle E is
[tex]\sin E=\frac{DF}{EF}[/tex]
[tex]\sin E=\frac{6}{10}[/tex]
[tex]\sin E=\frac{3}{5}[/tex]
The sine ratio of angle E is 3/5, therefore the correct option is B.
