Which section is MANDATORY in every Commercial Package Policy (CPP)?

Why this is the answer

A Commercial Package Policy combines multiple ISO commercial coverage parts under a single policy. The ONLY mandatory component is the Common Policy Declarations (named insured, policy period, premium) and the Common Policy Conditions (cancellation, changes, examination of books, inspections, premiums, transfer of rights). Every coverage part — Commercial Property, CGL, Commercial Inland Marine, Commercial Crime, Equipment Breakdown — is an optional module selected by the insured. This modularity lets insureds assemble a tailored program without purchasing unneeded coverages, per ISO standard CPP architecture cited in FL Outline §I.C.1.
