Answer:
Option (2) Lever of the second order.
Explanation:
First order lever - Fulcrum in between load and effort.
Second order lever - Load in between fulcrum and effort.
Third order lever - Effort is applied in between load and fulcrum.
A Standard bottle opener is a small machine in which the load is presented between the fulcrum and the effort applied. So, it is a second order lever.
