B. `x xx y - z `
C. `x Delta y phi z `
D. `x - y xx z`

Answer

C

Explanation

According to the meaning of the given symbols , `xphi y + z implies x lt y ne z`
Using the proper notations / symbols in option ( c) ,
we get `x Delta y phi z implies x cancelgt y lt implies x lt ne z`
Therefore `x phi y + z implies x Delta y phi z`.
