The 1:3 ratio means that the distance from A to the point is 1/4 of the distance from A to B.
The difference of y-coordinates is 10-8 = 2. 1/4 of that is 2·1/4 = 1/2, so the point of interest will have y-coordinate 8 + 1/2 = 8 1/2. This apparently corresponds to the first selection:
... (6 1/2, 8 1/2)

Answer:
4
Step-by-step explanation:
The common ratio r of a geometric sequence is obtained by dividing a term by its preceding term as follows:
1) 4/1=4
2) 16/4=4
for this sequence the common ratio
r=4
