Answer:
It is possible to have reasonable doubt about an element in a legal case, particularly if the evidence presented is not conclusive or there are alternative explanations for the element in question. Reasonable doubt is the standard used in criminal trials, and it refers to the level of certainty required for a defendant to be convicted of a crime. The prosecution must prove beyond a reasonable doubt that the defendant committed the crime in question. If there is any doubt about any element of the crime, the jury should find the defendant not guilty. Therefore, reasonable doubt can exist in an element if there is not enough evidence to prove it beyond a reasonable doubt.
