When helping others to set SMART goals,managers should:

A) set the goals for the subordinates.
B) make them general.
C) avoid modifying or updating original goals.
D) use intrinsic and extrinsic rewards.

SMART goals are most effective when they are accompanied by both intrinsic (internal satisfaction) and extrinsic (external rewards) motivators. This combination helps in keeping individuals motivated towards achieving their goals. Setting goals for subordinates, making goals general, and avoiding modifications are contrary to the principles of SMART goals, which emphasize specific, measurable, achievable, relevant, and time-bound objectives that may need adjustments as circumstances change.
