Elimination approach:
Anchor on the loan type with the least ambiguity: a Chattel loan is, by definition, secured against movable property such as livestock or machinery, so C must pair with (IV). This is true in options (1) and (4) only; options (2) and (3), which assign C to (III) and (I) respectively, are eliminated.
Between the two survivors, check A. A self-liquidating loan is structured so that the income it finances repays the loan within the same season, matching description (III). Option (1) assigns A - (III), while option (4) assigns A - (II), so option (4) is eliminated.
This confirms (A) - (III), (B) - (I), (C) - (IV), (D) - (II), which is option (1).
