Roots & Prefixes – MBA CET questions with solutions

Approach: Suffix '-aceous' = resembling / of the nature of; 'viola' = violet.

Solution: Violaceous = violet or purplish in colour → associated with colour.

Why the other options are wrong:
B, C: 'violent' is a false link – violaceous has nothing to do with violence or arson.
D, E: unrelated to the root.

Cetking shortcut: Words ending in '-aceous' after a colour/plant name (violaceous, olivaceous, rosaceous) describe colour or appearance.

Answer: A

Approach: Root 'olive' + '-aceous' (resembling).

Solution: Olivaceous = olive-green / of an olive colour → associated with colour.

Why the other options are wrong:
A, B, C, E: theatre, foundry, delinquency and reproduction have no link to 'olive'.

Cetking shortcut: Same pattern as violaceous – colour word + '-aceous'.
