(1) The Cumulative Link Models assumptions can be summarized as, conditional on (x1, … xk)
(2) Whether normality of error u, and thus normality of y conditional on (x1, … xk) can be assumed, is an empirical matter
and (3) Normality of error u translates into normal sampling distributions of the OLS estimators are all correct statements describing linear regression.
Answer:
