Option 4 : Statement II alone is sufficient to answer the question.

Maria covers 1000 m in 180 secs, so her speed will be 1000/180 = 5.55 m/s

Now, Naveen takes 16 secs to cover 80 m, so his speed will be 5 m/s.

Morrison covers 25 m for every 20 m covered by Naveen.

Ratio of distance covered by Morrison to that of Naveen is 5 : 4.

So the ratio of their speeds will be 5 : 4, that means speed of Morrison will be (5 × 5)/4 = 6.25 m/s.

Hence, Maria is not the fastest.
