Answer 1

The correct option is (c) Seat valve and butterfly valve

For explanation: There are many places in a piping system where it must be possible to stop the flow or divert it to another line. These functions are performed by valves. Seat valves, manually or pneumatically controlled, or butterfly valves, are used for this purpose.
