The least possible Venn diagram for the given statements is as shown below :- [ alt="F1 Savita SSC 8-7-22 D1" src="//storage.googleapis.com/tb-img/production/22/07/F1_Savita_SSC_8-7-22_D1.png" style="width: 267px; height: 60px;"> Conclusions: I. Some tomatoes are potatoes → False (As Some potatoes are onions and Some onions are tomatoes so, Some tomatoes are potatoes is possible but not definite.) II. No tomato is a potato → False (As Some potatoes are onions and Some onions are tomatoes so, No tomato is a potato is possible but not definite) ∴ Here, Conclusions I and II are false and both are possible and some + no is complementary pair. So, Either conclusion I or II follows. Hence, The correct answer is "Either conclusion I or II follows".
