__ allowed fuel delivery to be controlled electronically. a. Carbureted systems b. EFI systems C. Fuel rails d. Metering jets

## Step 1<br />The question is asking which system allows for electronic control of fuel delivery. The options provided are Carbureted systems, EFI systems, Fuel rails, and Metering jets.<br /><br />## Step 2<br />Carbureted systems, Fuel rails, and Metering jets are all components of an engine's fuel delivery system. However, they do not allow for electronic control of fuel delivery.<br /><br />## Step 3<br />On the other hand, EFI systems, or Electronic Fuel Injection systems, are designed to allow for electronic control of fuel delivery. This is done by using sensors to monitor various engine parameters and adjusting the fuel delivery accordingly.
