-
A.
WebAssembly.instantiate
WebAssembly.instantiate is a JavaScript API function that compiles and instantiates WebAssembly modules, returning ready-to-use module instances and their exported functions.
-
B.
WebAssembly.Module
WebAssembly.Module is a JavaScript object representing a compiled WebAssembly binary that can be efficiently instantiated and executed in web or other host environments.
-
C.
WebAssembly JavaScript Interface
The WebAssembly JavaScript Interface is the standard API that defines how JavaScript code interacts with and controls WebAssembly modules within web browsers and other host environments.
-
D.
WebAssembly.instantiateStreaming
WebAssembly.instantiateStreaming is a JavaScript API function that compiles and instantiates a WebAssembly module directly from a streamed source, such as a fetch response, for efficient loading and execution in the browser.
-
E.
WebAssembly.compile
WebAssembly.compile is a JavaScript API function that compiles WebAssembly binary code into an executable WebAssembly.Module object, enabling efficient reuse across multiple instantiations.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: WebAssembly.Instance Description of subject: WebAssembly.Instance is a JavaScript object representing a live, executable WebAssembly module with its associated state and exported functions.
