Checking each statement on its own merit: voltinism is a standard entomological term used to classify insects (univoltine, bivoltine, multivoltine) strictly by how many generations they complete in one year, so Statement I holds by definition. Separately, Morus alba (mulberry) is cultivated across northern Indian states as a long-lived perennial tree that is repeatedly pruned for leaf harvesting in sericulture rather than replanted each season, so Statement II also holds. Since neither statement can be faulted, both are correct.
