Some relationships have been expressed through symbols which are explained below:
o = greater than
`Delta` = not equal to
`xx` = not less than
`+` = equal to
`phi` = not greater than
`nabla` = less than
`a nabla b nabla c` implies

Options

A. `a Delta b phi c`
B. `a phi b + c `
C. `a o b + c `
D. `a o b xx c `

Answer

A

Explanation

`a nabla b nabla c `
`implies a lt b lt c`
Option (1) `a Delta b phi C implies a gt b le c or , a lt b le c `
Option (2)
`a phi b + c implies a le b = c `
Option (3)
`a 0 b + c implies a gt b = c `
Option (4) `a 0 b xx c implies a gt b ge c `
