P `o+` Q means P is greater than Q.
P `underline"©"` 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.
M @ L, O `o+` P, M = N, O `underlinecancel("@")` N
Conclusions: I. M `o+` O II. M = O

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: `M lt L, O gt P, M = N, O le N`
Conclusions: I. `M gt O` II. M = O
Combining M = N and `O le N`, we have `O le M.` This gives `M gt O` or M = O. (Check 3)
