Using the Taylor series expansion, What is the first term of the truncation error of the finite difference equation (( frac{ partial u}{ partial x})_{i,j}= frac{u_{i+1,j}-u_{i,j}}{ Delta y} )?

A. (-( frac{ partial^2 u}{ partial x^2})_{i,j} frac{ Delta x}{2} )
B. (( frac{ partial^2 u}{ partial x^2})_{i,j} frac{ Delta x}{3} )
C. (-( frac{ partial^2 u}{ partial x^2})_{i,j} frac{ Delta x}{3} )
D. (( frac{ partial^2 u}{ partial x^2})_{i,j} frac{ Delta x}{2} )
