Complete step-by-step answer:
 5,8,6,4,10,15,18,10 given data
Arrange data in ascending order 4,5,6,8,10,10,15,18
Here 10 occur most often
Hence, 10 is the model of given data
Answer is (2)

Note: For more understanding let's have another example
4,7,8,10,10,10,10,18,18
We can see that 10 occurs most often 10 is modal of the given data.
For larger values the data having higher frequency is the modal value of the given data set
