| What occurs within the tubes of the device labeled "23" shown in the illustration? Illustration MO-0111 |
| A) The feedwater flowing through the inside of the tubes is being heated by the jacket water on the outside of the tubes. |
| B) The heat from the jacket water passing within the tubes is being transferred to the feedwater on the outside of the tubes. |
| C) The heat of combustion from the engine is being transferred azeotropically, adding latent heat to the entering jacket water. |
