B Correct answer
Explanation

RS-232 is a single-ended signaling standard where voltage is measured relative to a common ground, making it susceptible to noise over long distances. Differential signaling, used in standards like RS-422 and RS-485, uses two complementary signals to cancel noise, which RS-232 does not employ.
