Answer:
Option C is correct.
Step-by-step explanation:
C- Survey every tenth student entering the school one morning.
This is because the survey is related to the entire student population of a school as they want to know which type of speaker the students prefer to invite to an assembly.
Reasons for incorrect options:
Option A is not true as it will relate to a mall survey. Option B is also incorrect as it will only survey few students of a student council that cannot represent a whole population. Option D is related to basketball survey, it has nothing to do with any speaker chosen for an assembly.
