Option D: None of the above
To solve this problem, we need to arrange the students around the circular table based on the given conditions.
     ● Condition 1: B and D sit neither adjacent to C nor opposite to C.  
     ● Condition 2: A sits in between E and D, and F sits in between B and H.  
     Let's analyze these conditions step by step:
     ● Step 1: Place A, E, and D. Since A is between E and D, we can have the arrangement: E - A - D.  
     ● Step 2: Place F, B, and H. F is between B and H, so we can have the arrangement: B - F - H.  
     ● Step 3: Consider the placement of C. Since B and D cannot be adjacent or opposite to C, C cannot be placed directly next to or opposite B or D.  
     ● Step 4: Arrange the remaining students. We have the following possible arrangement:  
           ○ E - A - D - G - C - B - F - H
       In this arrangement:
           ○ A is between E and D.
           ○ F is between B and H.
           ○ B and D are neither adjacent to nor opposite C.
     Now, let's evaluate the options:
     ● Option A: B sits in between A and G.  
           ○ In our arrangement, B is not between A and G. So, this option is incorrect.
     ● Option B: C sits opposite to G.  
           ○ In our arrangement, C is not opposite G. So, this option is incorrect.
     ● Option C: E sits opposite to F.  
           ○ In our arrangement, E is not opposite F. So, this option is incorrect.
     Since none of the options A, B, or C are correct based on the arrangement, the correct answer is Option D: None of the above.
