Answer 1

The correct option is B due to osmosis bacteria lose water on salted meat or candid fruit and die

Preservation of meat and fruits can be done by salting and adding sugar as a bacterial body can be considered as a dilute solution and salted meat or sugared fruits as a concentrated solution. So the movement of water molecules occurs from the bacterial body to salted meat or sugared fruits and they die.
