B. A person and the earth
Explanation:
The gravitational force of attraction depends on the masses (M and m) of the object and distance (d) between them.

where G is the gravitational constant.
It is given that the distance between first and second objects is same in the given options. This means the gravitational attraction would be largest for the pair which would have largest mass. The Earth has greatest mass followed by a person, then a small bird and an ant has the least mass.
Thus, LARGEST gravitational attraction be found between a person and the earth.
