If h(n) is causal and h(n)=he(n)+ho(n),then what is the expression for h(n) in terms of only he(n)?

h(n)=2he(n)u(n)+he(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 0

h(n)=2he(n)u(n)+he(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 1

h(n)=2he(n)u(n)-he(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 1

h(n)=2he(n)u(n)-he(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 0

1.	If h(n) is causal and h(n)=he(n)+ho(n),then what is the expression for h(n) in terms of only h_e(n)?
A.	h(n)=2h<sub>e</sub>(n)u(n)+h<sub>e</sub>(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 0
B.	h(n)=2h<sub>e</sub>(n)u(n)+h<sub>e</sub>(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 1
C.	h(n)=2h<sub>e</sub>(n)u(n)-h<sub>e</sub>(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 1
D.	h(n)=2h<sub>e</sub>(n)u(n)-h<sub>e</sub>(0)‚âà√≠¬¨‚Ä¢(n) ,n ‚Äö√Ñ√∂‚àö¬¢‚Äö√Ñ¬¢ 0
