To solve the problem \(-1 \frac{3}{4} \div \frac{2}{5}\), we first need to convert the mixed number \(-1 \frac{3}{4}\) into an improper fraction.

  1. Convert \(-1 \frac{3}{4}\) to an improper fraction: \[ -1 \frac{3}{4} = -\left(1 \cdot 4 + 3\right) / 4 = -\left(4 + 3\right) / 4 = -\frac{7}{4} \]

  2. Now, we divide \(-\frac{7}{4}\) by \(\frac{2}{5}\). Dividing by a fraction is the same as multiplying by its reciprocal: \[ -\frac{7}{4} \div \frac{2}{5} = -\frac{7}{4} \cdot \frac{5}{2} \]

  3. Multiply the fractions: \[ -\frac{7 \cdot 5}{4 \cdot 2} = -\frac{35}{8} \]

  4. The result \(-\frac{35}{8}\) can be expressed as a mixed number: \[ -\frac{35}{8} = -4 \frac{3}{8} \]

Thus, the quotient in simplest form is \( \text{negative } 4 \text{ and } 3 \text{ eighths} \).

The correct response is: −4 and 3 eighths
