To subtract fractions, we need a common denominator. We can convert the whole number $-3$ to a fraction with denominator $5$ by writing $-3 = -\frac{15}{5}$. Therefore, we have: $$ -3 - \frac{4}{5} = -\frac{15}{5} - \frac{4}{5} = -\frac{19}{5} $$ The answer is in lowest terms, and is negative, so the correct choice is B.
