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

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

A

Explanation

Statements: `I le R, D lt I, E = C, R gt E`
Conclusions: I. `R gt C` II. I = R
I follows from `R gt E` and E = C. II can.t be true as there are no equalities involving I or R in given statements (Tip 7: quick method).
