Explanation:

Step1: Identify the lowest scores

The scores are 85, 56, 67, 90, 95, 86, 0, 83, 100, 88. The two lowest scores are 0 and 56.

Step2: Calculate the sum of remaining scores

Sum of remaining scores = 85+67+90+95+86+83+100+88 = 694

Step3: Calculate the number of remaining scores

There were originally 10 scores, and 2 were dropped. So the number of remaining scores is 8.

Step4: Calculate the average

Average = $\frac{694}{8}=86.75$

Step5: Round to the nearest tenth

Rounding 86.75 to the nearest tenth gives 86.8

Answer:

C. 86.8
