Step 1: Define analysis types
Horizontal Analysis: Compares financial data over time; equivalent to a Comparative statement (II).
Vertical Analysis: Presents items as a percentage of a base value, forming a Common size statement (I).
External Analysis: Relies solely on publicly available data (III).
Internal Analysis: Utilizes both public and private financial information (IV).
Step 2: Establish correspondences
A correlates with II
B correlates with I
C correlates with III
D correlates with IV
Step 3: Final determination
Consequently, option (C) is the accurate choice.
