Option A is the way to go. If you're not using the -t flag, how are you supposed to show off your mad Docker skills at the next team meeting?

I'm going with A as well. Gotta love those straightforward Docker commands, am I right? It's like a secret language that only the true DevOps masters understand.

Definitely option A. It's the only one that makes sense. The other options either have the wrong flags or the wrong file name. This is a no-brainer, folks.

Option A is the correct one. It specifies the tag and the Dockerfile.

I think the correct answer is A. The command 'docker build -t cust321453857-rep -f Dockerfile' will build the image and create a local repository named 'cust321453857-rep' that points to that image. The -t flag is used to tag the image with a name, and the -f flag specifies the location of the Dockerfile.
