The Bohr model of an atom is contradicted by

Given below are two statements:
Statement $I:$ According to Bohr's model of hydrogen atom,the angular momentum of an electron in a given stationary state is quantised.
Statement $II:$ The concept of electron in Bohr's orbit,violates the Heisenberg uncertainty principle.
In the light of the above statements,choose the most appropriate answer from the options given below:

If uncertainty in the position of an electron is zero,the uncertainty in its momentum would be

What is the value of $\Delta v \cdot \Delta x$ for an electron? What does it indicate?

The Bohr model of the atom is contradicted by

The effect of the uncertainty principle is significant only for the motion of microscopic particles and is negligible for macroscopic particles. Justify the statement with the help of a suitable example.
