C Correct answer
Explanation

The sentence is a warning: 'Watch out or you will meet with an accident.' 'Or' here introduces a consequence in a conditional structure. 'And' would connect similar ideas, 'because' gives a reason, and 'unless' creates a different conditional meaning that would need to start the sentence.
