Answer: A. 1
Explanation:
The term can be simplified as c (c^8 + 2)
-- c term has degree 1 .
-- c^8 + 2 term has degree 8 .
--Here highest degree is maximum of all degrees of terms i.e 8 .
--Hence the leading term of the polynomial will be the terms having highest degree i.e c^8 + 2 .
--c^8 + 2 has coefficient 1 .
