Charges cannot flow without:
a. voltage.
b. low resistance.
c. high resistance.
d. a gap in the circuit.

Voltage

Explanation:

Charges cannot flow without voltage which is also known as electromotive force. The electromotive force is known to be the driving force for current in an electric circuit. This emf or battery is the source voltage that has both positive and negative terminals. Current flows from out from the positive terminal of the battery. This means that the arrangement of the polarity of the battery determines the direction of flow of the electric current through an electric circuit. The flow of current in a DC circuit is in one direction i.e either clockwise or anticlockwise.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
