Inefficiency in a lever typically occurs due to factors such as friction and mechanical advantage. In the options provided, the most relevant choice related to inefficiency would be:
**where the fulcrum touches the bar**
This is because friction at the fulcrum can lead to loss of efficiency in the work done by the lever.
