A black streak upon rendering in cycles.
Noticed a black streak upon rendering in Cycles. How do I resolve this issue and what caused it?
I am a complete beginner to blender.

$\begingroup$ the big "O" shaped black area is a shadow. The small vertical black line is also a shadow - caused by a crease in the topping. $\endgroup$– Markus von BroadySep 19 at 12:30

You have some weird inner topology there causing the black streak. Select the donut dripping mesh, go to edit mode and choose Select > Select All by Trait > Interior Faces. With enabled X-Ray mode you should see something like this:
Hit the Del key and select Faces to delete all this inner stuff and the black streak should be gone.
