  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R is not the correct explanation of A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer

A is true but R is false.

Explanation
Arithmetic operations on two Series objects take place on matching indexes. When performing operations on objects with non-matching indexes, Pandas aligns the indexes and adds values for matching indexes, resulting in NaN (Not a Number) for non-matching indexes in both objects.
