When a theory is disproved by further evidence, which of the following occurs?
a.) it should be considered a failure.
b.) it adds to scientific knowledge.
c.) it becomes a law.
d.) new data must be found to support it.

When a theory is disproved by further evidence, then a new data must be found to support it.

There must be new data that has to be developed with logical approach and must be supported by evidence.
