Question

**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. A). Both (A) and (R) are true and (R) is the correct explanation for (A). B). Both (A) and (R) are true and (R) is not the correct explanation for (A). C). (A) is true and (R) is false. D). (A) is false but (R) is true.

The correct answer is Both (A) and (R) are true and (R) is not the correct explanation for (A).. Both statements are factually correct independent of each other. A Series is 1D and a DataFrame is 2D. Also, if indices are not provided, both default to a numeric index starting from 0. However, the default indexing behavior (Reason R) does not logically explain the dimensionality difference of the data structures (Assertion A).
