   An automation engineer is writing a PyEZ script to configure multiple Junos devices. The script uses a Jinja2 template that includes a conditional block based on the device role. The engineer needs to render the template with different variables for each device and load the configuration. The script currently has a `Device` object named `dev` and a dictionary `device_vars` containing role-specific data. Which approach correctly renders the template and loads the configuration for each device?

   • ARender the template manually with `jinja2.Template` and then call `dev.load_config(rendered)`
   • BCall `dev.load(template_path='config.conf', template_vars=device_vars, format='set')` for each device
   • CCall `dev.load('config.conf', **device_vars)` for each device
   • DUse `dev.load(template='config.conf', vars=device_vars)` for each device
