Answer:
OPTION A: [tex]$ \frac{6}{7} $[/tex]
Step-by-step explanation:
Co-efficient of a polynomial is the multiplicative term for some term of the polynomial.
For example, Consider the quadratic polynomial [tex]$ ax^2 + bx + c = 0 $[/tex] then the co-efficient of [tex]$ x^2 $[/tex] is a.
Similarly, we are asked the co-efficient of [tex]$ \frac{6}{7} xy $[/tex]
Clearly, the co-efficient of [tex]$ \frac{6}{7} xy$[/tex] is [tex]$ \frac{6}{7} $[/tex].
