P `alpha` Q means P is greater than Q.
P `beta` Q means P is either greater than or equal to Q.
P `gamma` Q means P is equal to Q.
`delta` Q means P is smaller than Q.
`eta` Q means P is either smaller than or equal to Q.
Statemens: `H gamma A, N delta A, C alpha H, N eta D`
Conclusions: I. `C alpha N` II. `A gamma D`

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: `H = A, N lt A, C gt H, N le D`
Conclusions: I. `C gt N` II. A = D
From, `C gt H` and H = A we get `C gt A`. Now, `C gt A` and `N lt A` gives `C gt A gt N` to give `C gt N`. A = D is false as there are no equalities with D in the given statements.
