The correct option is D Brinjal
According to number of carpels, gynoecium is monocarpellary, bicarpellary, tricarpellary and multicarpellary. Brinjal has bicarpellary, syncarpous, bilocular or tetralocular gynoecium due to presence of pseudoseptum multiple ovules on axile placentation with superior and obliquely placed ovary.
Banana has multicarpellary gynoecium with an inferior ovary with 3 locules, each with numerous axile ovules.
Pisum has monocarpellary, unilocular gynoecium with ovules on marginal placentation and superior ovary. Mustard has bicarpellary gynoecium separated by a persistent false partition, replum. The bilocular superior ovary with few to many ovules is present on parietal placentae.
Therefore, the correct answer is option D.
