You Answered:

Selection BThe coefficient has increased, because signs of atherosclerosis are correlated.

INCORRECT

The correct answer is (c). The coefficient has decreased, because signs of atherosclerosis are correlated. A sign related to a disease is more frequent in patients who have other signs of that disease. A positive correlation implies that multivariable regression coefficients are smaller than univariable coefficients.
