$$F=\frac{9}{5}C + 32$$

If F = 85, then $$85=\frac{9}{5}C + 32$$;

$$53=\frac{9}{5}C$$;

$$C=53*\frac{5}{9} \approx 54*\frac{5}{9}=30$$.

Alternative approach, work around by plugging in the options as this question talks about approximate values

Use options (C) the middle value ( As the options are in ascending order )

$$F=\frac{9}{5}*C + 32$$

Or, $$30*\frac{9}{5} + 32 = 86$$
