ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions.

Answer:
Option C is the correct option.
Step-by-step explanation:
[tex]f(x) = a {x}^{2} + bx + c[/tex]
Discriminant = [tex] {b}^{2} - 4ac[/tex]
Given d = 15
When discriminant D > 0 --> roots are real and distinct. ( unequal )
So , [tex] {3}^{rd} [/tex] option has real and distinct roots.
Hope this helps..
Best regards!!
