Scientific name of the Dammer bee is

Answer: Option B

Scientific name of the Dammer bee is Melipona irridipennis.
The Indian stingless bee or dammar bee, Tetragonula iridipennis, is a species of bee belonging to the family Apidae, subfamily Apinae.
Many older references erroneously placed this species in Melipona, an unrelated genus from the New World and until recently it was placed in Trigona, therefore still often mistakenly referred to as Trigona iridipennis.
