Select the odd one out from the following.

FLOW, FLED, and FLING are verbs. FLOOR is primarily a noun. Therefore the odd one out is FLOOR.

• FLOW — verb. Example: "Water flows down the river."

• FLED — verb (past tense of 'flee'). Example: "He fled the scene."

• FLING — verb. Example: "She flung the ball."

• FLOOR — primarily a noun meaning the surface of a room. Example: "The floor is clean."

Note: Although 'floor' can also be used as a verb in other contexts (for example, 'He was floored by the news'), in this set the intended sense is the noun 'floor', which makes it different from the other three words that function as verbs.

Final answer: FLOOR
