Question No 3:

Assertion (A): A Series is a one dimensional array and a DataFrame is a two-dimensional array containing sequence of values of any data type. (int, float, list, string, etc.)

Reason (R): Both Series and DataFrames have by default numeric indexes starting from zero.

(i) Both (A) and (R) are true and (R) is the correct explanation for (A).

(ii) Both (A) and (R) are true and (R) is not the correct explanation for (A).

(iii) (A) is true and (R) is false.

(iv) (A) is false but (R) is true.
