Although, profiles of different types of soil differ markedly with respect to their physico-chemical and
biological properties; the following diagram shows a typical hypothetical soil profile with its 5 principal
horizons [O to R].

Study the given diagram. The characteristics [Q to U] related to various horizons and the names of
horizons [i to v] are tabulated below:

Make the correct matches of the characteristics [Q to U] with the horizons [i to v] and choose the correct
option:
