P `o+` Q means P is greater than Q.
P `underlinecancel("©")` Q means P is either greater than or equal to Q.
P = Q means P is equal to Q.
P @ Q means P is smaller than Q.
P `underlinecancel("@")` means P is either smaller than or equal to Q.
Statements: A @ B, D `underlinecancel("@")` E, C = D, C `underlinecancel("©")` B
Conclusions: I. `E o+ B` II. B = E

Options

A. If only I is true
B. if only conclusion II is true
C. if either conclusion I or II is true
D. if either I nor II is true

Answer

C

Explanation

Statements: `A lt B, D le E, C = D, C ge B`
Conclusions: I. `E gt B` II. B = E
Combining `D le E` and C = D we get `C le E`. This, combined with `C ge B`, Gives `B le C le E` which gives `B le E.` So, either `B lt E` or B = E. (Check 3)
