Answer:
The table C correctly shows the ratio 8:1 for each grade
Step-by-step explanation:
Let
x ----> the number of students
y ----> the number of adults
we know that

<u><em>Verify each table</em></u>
Table A
grade 6

Multiply in cross
----> is not true
Table B
grade 6

Multiply in cross
----> is not true
Table C
<u><em>grade 6</em></u>
\frac{96}{12}=\frac{8}{1}
Multiply in cross

----> is true
<u><em>grade 7</em></u>

Multiply in cross

----> is true
<u><em>grade 8</em></u>
\frac{136}{17}=\frac{8}{1}
Multiply in cross

----> is true
therefore
The table C correctly shows the ratio 8:1 for each grade
Table D
<u><em>grade 6</em></u>

Multiply in cross
----> is not true
(50 yards/minute) x (3 feet/yard) x (1 minute / 60 seconds)
= (50 · 3 · 1 / 60) (yard-feet-minute) / (minute-yard-second)
= 2.5 feet/second .
