hope it useful means mark as brainlist please.

Step-by-step explanation:

(B) 270°, 90° We know that, measure of complete angle of clock is 360o.

From the figure, we can say that angle at 2 = (9/12) × 360o= 270o Then, angle at 1 = 360o – 270o = 90o Therefore, measures of the two angles between hour and minute hands of a clock at 9 O’ clock are 270o and 90 degree.
