The correct option is
C Both A and B
A poster is generally made in this order:
1. The name of the organisers
2. A graphic image that represents the poster
3. The heading
4. The message/details of the event
5. The date, place and time when the event will be held
6. Contact details of a person for attending the event
Hence, blank 44 is filled with the Date, Venue (place) and Time.
Option C: The Date, Time and Venue are generally mentioned in one line itself. Hence options A and B are both used in blank 44.
Hence C is incorrect.
So, options A and B are both individually incorrect.
Option
D is incorrect because the answer lies in C.
