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.
M = I, A `o+` M, T `underlinecancel("@")` I, T = K
Conclusions: I. M = K II. K @ M

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 = I, A gt M, T le I, T = K`
Conclusions: I. M = K II. `K lt M`
We have T = K and M = I. So, replacing T by K and I by M in `T le I` we get `K le M` which means that either K = M or `K lt M`. (check 3)
