B) 20.31
C) -4.53
D) 26.06

Plugging the values into the function $f(x, y, z) = \frac{xy + z}{x + yz}$, we get $f(16.92, 1.56, -3.76) = \frac{16.92 \times 1.56 - 3.76}{16.92 + 1.56 \times -3.76}$. Calculating the numerator and denominator separately, we get approximately $26.3952 - 3.76 = 22.6352$ for the numerator and $16.92 - 5.9056 = 11.0144$ for the denominator. Dividing these, $22.6352 / 11.0144 ≈ 2.05$.
