According to Taylor, is an extension of the principle of division of work and specialisation to the shop floor.

Option 1 -> Functional organisation refers to grouping activities by functions like production, marketing, finance at the organizational level, not specifically at the shop floor.

Option 2 -> Standardisation involves establishing uniform standards for work methods, tools, and time, but doesn't directly relate to division of work among supervisors.

Option 3 -> Functional Foremanship is Taylor's technique where instead of one foreman, eight specialized foremen supervise workers - each handling specific functions like speed, quality, repairs, etc., thus extending specialization to supervision level.

Option 4 -> Divisional Foremanship is not a recognized concept in Taylor's Scientific Management theory.

Hence, Option 3: Functional Foremanship -> Taylor proposed replacing the single foreman system with eight specialized foremen (four in planning, four on shop floor), each expert in their specific function. This directly extends the principle of division of work and specialization to the supervisory level on the shop floor -> correct
