Q. Assertion (A) It is impossible to determine the exact position and exact momentum of an electron, simultaneously.
Reason (R) The path of an electron is clearly defined.

Solution:

According to Heisenberg's uncertainty principle, the exact position and exact momentum of an electron cannot be determined simultaneously, thus, path of an electron in an atom cannot be defined clearly.
