Are the options correct??? (Question: 76132.0 )

I think the options are not correct..

Question:
The reflex angle between the hands of a clock at 11:30 is?
Options:
A) 200o
B) 195o
C) 300o
D) 360o
Solution:

At 11:30, the minute hand is at 6 and it makes an angle = 6*30 = 180 deg from 12.

At 11:30, the hour hand is between 11 and 12 and it makes an angle = (11*30)+(30*30)/60 = 330+15 = 345 degree.

At 11:30, the minute hand and the hour hands make an angle = 345–180 = 165 deg from 12. And the larger reflex angle = 360–165 = 195 degree.
