When the -mod=vendor flag is used with the go build command, Go will use the dependencies located in the _____ directory.

When you use the "-mod=vendor" flag with the "go build" command in Go, the compiler will use the dependencies located in the "/vendor" directory. This means that the project will build using the versions of dependencies that you have vendored in your project's "/vendor" directory. It provides a way to build your project in isolation from the global module cache and ensures that the versions you specified in your "go.mod" file are used.
