HTML? Really? That's for web pages, not defining a REST API. C is the way to go.

I agree, C is the right choice. WSDL is for SOAP services, not REST.

C) Open API(JSON/YAML) is definitely the correct answer. That's the file format used to define the API contract for a REST service.

I’m pretty confident that Open API is the right choice, but I’m unsure about the HTML option.

I feel like Jar/Zip files might be used for deployment, but I can't recall if they're necessary for the service itself.

I remember practicing a question like this, and I think WSDL is more for SOAP services, not REST.

I think we need the Open API file for creating a REST service, but I'm not sure about the others.

I'm pretty sure the correct answers are C) Open API(JSON/YAML) and D) Jar/Zip. The Open API file defines the API, and the JAR or ZIP file contains the actual service implementation.

I'm a bit confused on this one. I thought we needed a JAR or ZIP file to create the service implementation, but I'm not sure if that's the file the question is asking about. I'll have to review my notes on REST services.

Okay, let me see. For a REST service, we use an Open API definition, not a WSDL. So I'm pretty confident that C is the right answer here.

Hmm, I'm not sure about this one. I know we need some kind of API definition, but I can't remember if it's WSDL or Open API. I'll have to think this through carefully.
