The solution of

\left(y\left(1+x^{-1}\right)+\sin y\right) \mathrm{d} x+

(x+\log x+x \cos y) \mathrm{d} y=0

View answer and explanation

Correct option: C

x y+y \log x+x \sin y=C

Option C (

x y+y \log x+x \sin y=C

) is correct because the given differential equation is exact and its solution is found by integrating the terms.
