Step 1: Nature of SCC (Special Conditions of Contract).
- SCC are clauses that supplement the General Conditions of Contract (GCC).
- They deal with project-specific requirements, especially financial, mobilization, and site-related provisions.
Step 2: Analyze options.
- (A) Scope and performance of work → general clause, found in GCC.
- (B) Site mobilization advance → explicitly mentioned in SCC, since it is project-specific and varies from contract to contract.
- (C) Labour regulation → typically part of labour laws and compliance, not SCC-specific.
- (D) Arbitration and law → generally in GCC.
Step 3: Conclusion.
Thus, the correct criterion mentioned in SCC is site mobilization advance.
\[
\boxed{\text{Site mobilization advance}}
