The "unless" rule functions by inverting the meaning of the preceding part of the statement. In other words, when "unless" is used, the intention is to indicate that the statement following "unless" will occur if the condition outlined in the initial part is not met. This is why option A is the correct answer.

Options B, C, and D are incorrect because the "unless" rule does not combine the meanings of the parts, negate the entire statement, or reinforce the main intention. Instead, it specifically flips the meaning of the preceding part to convey a conditional relationship between two parts of the statement.
