The correct option is (B):
Explanation:
The total score of John in the three tests is calculated as:
\[85 \times 3 = 255\]
(A): John's highest score is 95. Therefore, the sum of the other two scores is:
\[255 - 95 = 160\]
From this, we cannot determine the lowest score.
(B): The sum of the two highest scores is:
\[92 \times 2 = 184\]
The lowest score can then be found as:
\[255 - 184 = 71\]
Thus, Statement B alone is sufficient to determine the lowest score.
