The insert will result in an error as it violates the WITH CHECK OPTION on view V2. The WITH CHECK OPTION ensures that any row inserted through view V2 must satisfy the condition defined in V2, which is col1 < 40. Since the insertion through V3 implies an insertion through V2 as well, the value 30 must satisfy the condition col1 < 40 defined in V2. Therefore, the answer stating that it results in an error due to the violation of the WITH CHECK OPTION on view V2 is correct.
