Dear Student,

triangle = >
square = <
phi = =
star = ≠

So, C triangle A i.e. C>A _____(1)

A square B i.e. A<B _________(2)

D phi B i.e. D=B __________(3)

B square C i.e. B<C

Combine (1), (2), (3) and (4) together,

C>B=D>A<C _______(5)

Option(a); D triangle C i.e. D>C [Not possible because we get D<C]
Option(b); D square C i.e. D<C [Yes its correct]
Option(c); A triangle C i.e. A>C {Not Possible because we have A<C}
Option(d); B star D i.e. B≠D[Not possible because we have B=D]

Hence, Option(b) is the only correct answer.
