Question
A development team needs to containerize an application named 'cust484705142'.

Explanation
The correct Docker build syntax to name a local repository and specify a Dockerfile is: docker build -t <repository-name> -f <Dockerfile>. The -t flag tags the resulting image with the local repository name, and -f Dockerfile explicitly names the file to use (found in the current folder). Answer B has no -t flag and uses a wrong filename. Answer C has incorrect syntax with no flags. Answer D uses the wrong filename Dockerfile.txt instead of Dockerfile.
