Given below are two statements:
Statement I: For diamagnetic substance $$-1 \leq x < 0$$, where x is the magnetic susceptibility.
Statement II: Diamagnetic substance when placed in an external magnetic field, tend to move from stronger to weaker part of the field. In the light of the above statements, choose the correct answer from the options give below.

In an experiment with vernier callipers of least count 0.1 mm, when two jaws are joined together the zero of vernier scale lies right to the zero of the main scale and 6$$^{th}$$ division of vernier scale coincides with the main scale division. While measuring the diameter of a spherical bob, the zero of vernier scale lies in between 3.2 cm and 3.3 cm marks and 4$$^{th}$$ division of vernier scale coincides with the main scale division. The diameter of bob is measured as
