A roller chain drive is to transmit a design power of 9.0 kW with the faster shaft having a speed of 84 rpm. Select the most suitable chain size and type of lubrication from the following options if the pinion has 15 teeth:

1 - Pitch of 25.4 mm, oil bath or disc lubrication,

2 - Pitch of 19 mm, drip feed lubrication,

3 - Pitch of 25.4 mm, drip feed lubrication,

4 - Pitch of 19 mm, drip feed lubrication,
