已知$$f\left( x \right)$$和$$g\left( x \right)$$)是两个二次项系数均为$$1$$的二次函数．若$$g\left( 6 \right)=35$$﹐$$\frac{f\left( -1 \right)}{g\left( -1 \right)}=\frac{f\left( 1 \right)}{g\left( 1 \right)}=\frac{21}{20}$$，则$$f\left( 6 \right)=$$~\uline{~~~~~~~~~~}~．
选项为:A:$$31$$  B:$$32$$  C:$$33$$  D:$$34$$  E:$$35$$  请回答其中一个选项.
