4.  Some grapes are not tasteless.
5.  No grape is tasteless.

• A. cea
• B. bdc
• C. cbd
• D. eac

Answer 1

From those given options , option B and C we can eliminate first as in both cases the third statement is NOT a conclusion drawn from the preceding two statements.

Now coming to option D,  No grape is tasteless -> Grapes are not sour --- all sour things are tasteless , here 3 rd statement is not a conclusion from precedig two statements. 2nd statement should be  conclusion , not the 3rd statement as in this case.

For option A,

All sour things are tasteless --->  No grape is tasteless ---> so it is clear that Grapes are not sour.  here 3rd statement is a conclusion from preceding 2 statements .

Hence, correct option is option A .
