Show answer & explanation
Correct answer: C
In First-Order Logic (FOL), the basic syntactic symbols are those used to form well-structured formulas. These include:
Constants (A) ✅ → Represent specific objects in the domain
Predicates (C) ✅ → Represent properties or relations among objects
Functions (E) ✅ → Map objects to objects
The following are not syntactic symbols of FOL:
Domain (B) ❌ → Part of semantics, not syntax
Temporal (D) ❌ → Related to temporal logic, not first-order logic
✔ Correct combination:
A. Constant
C. Predicate
E. Function
