Final answer:
The definition of 'transact' in relation to insurance includes solicitation, underwriting, negotiations, and contract execution, with underwriting being the exception.
Step-by-step explanation:
The transact definition as applied to insurance includes solicitation, underwriting, negotiations preliminary to execution, and execution of a contract of insurance. Therefore, option 2: underwriting is not included as a definition of 'transact' as applied to insurance. Underwriting refers to the process of evaluating and assessing risk before accepting or rejecting an insurance application.
