Answer:

The correct option is B.

Step-by-step explanation:

If two cords intersect outside a circle then the measure of the angle formed is one-half the absolute difference of the measures of the intercepted arcs.

[tex]\angle DCB=\frac{1}{2}(arc(AE)-arc(BD))[/tex]

[tex]\angle DCB=\frac{1}{2}(100-30)[/tex]

[tex]\angle DCB=\frac{1}{2}(70)[/tex]

[tex]\angle DCB=35[/tex]

The measure of angle C is 35 degree. The correct option is B.
