Which is in third quadrant, therefore cosine is negative hence
C)
Which is in third quadrant, therefore tangent is positive hence
D)
Which is in third quadrant, therefore cosec is negative hence
not defined
E)
Which is in third quadrant, therefore secant is negative hence
F)
Which is in third quadrant, therefore tangent is positive hence
not defined
Hence only and
have value -1
