Two Physics Students Carefully Measure the Position of an Object

Two physics students carefully measure the position of an object and report the following results:
Student 1: To get to the object, one should go 3.0 m north and then 4.0 m east.
Student 2: To get to the object, one should go 6.0 m south. Which one of the students is correct?

A) Student 1 only.
B) Student 2 only.
C) Either student 1 or student 2, but not both, depending on the reference frame chosen by each of the students.
D) Both student 1 and student 2 could be right, depending on the reference frame chosen by each of the students.
E) Neither student 1 nor student 2, irrespective of the choice of the reference frames.
