The answer will be none of these.

531 : 99 = $\frac{531}{99} = \frac{177}{33} = \frac{59}{11}$

451 : 55 = $\frac{451}{55} = \frac{41}{5}$

321 : 44 = $\frac{321}{44}$

642 : 66 = $\frac{642}{66} = \frac{321}{33} = \frac{107}{11}$

212 : 11 = $\frac{212}{11}$

Here, the ratio of 531 : 99 is not equal to the any of the given options.

Hence, the answer will be none of these.
