Let (a,) and (b.) are two sequences. Then choose the incorrect. (A) (A)If (a, + b,) and (a, b,) are both convergent. Then (a,) and (b) are convergent (B) If (a, - b,) and are both convergent. Then (a,) and (b) are convergent ba (C) if (a, + b) and (a, - b.) are both convergent. Then (a,) and (b) are convergent (D) lf (a, + b) and (a,- b,) are both convergent. Then
