A)5 to 10
B)12 to 14

The quantization effect on filter coefficients can be avoided by using a sufficient number of bits to represent the coefficients. In cascade form of realization, the number of bits required depends on the number of stages in the cascade. For a typical cascade filter with 10-20 stages, 12-14 bits are usually sufficient to avoid the quantization effect.
