Answer this mathematics question fast

We have,ab=3b=3a   ...(1)and,bc=63a×c=6    [using 1]c=2a     ...(2)and,ac=11a(2a)=11    [using 2]a2=112a=112a=2.35Put the value of a in (2), we getc=2×2.35c=4.70Put the value of a in (1), we getb=32.35b=1.27So, abc=2.35×4.70×1.27abc=14.02So, acoording to options you can consider 14.07 as the correct option.
