A mule project contains MySQL database dependency. The project is exported from Anypoint Studio so that it can be deployed to Cloudhub. What export options needs to be selected to create the smallest deployable archive that will successfully deploy to Cloudhub?

A. Select both the options 1) Attach project sources 2) Include project module and dependencies

B. No need to select any of the below options 1) Attach project sources 2) Include project module and dependencies

C. Select only below option 2) Include project module and dependencies

D. Select only below option 1) Attach project sources

C. Select only below option 2) Include project module and dependencies

Explanation:
You can choose Attach Project Sources to include metadata that Studio requires to reimport the deployable file as an open Mule project into your workspace. You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace. But requirement here is to create smallest deployable archive that will successfully deploy to Cloudhub. Hence we can ignore this option.
We need to select Include project module and dependencies.
