Explanation
Lua is the scripting language used to build a DataScript - specifically in the context of F5 BIG-IP, where DataScripts are written in Lua to manipulate HTTP traffic at Layer 7. Node.js (B) is a JavaScript runtime environment for server-side applications, not a DataScript language. Python (C) is a general-purpose language with no role in F5 DataScripts. Tcl (D) is the language used for iRules - F5's older traffic scripting feature - making it the trickiest distractor since it's closely related but distinct from DataScripts.
Memory tip: Think "DataScript → Lua" - Lua is lightweight and embeddable, fitting the inline scripting nature of DataScripts, while Tcl belongs to the older iRules system. If you remember "iRules = Tcl, DataScripts = Lua," you won't confuse the two on exam day.
