To multiply 4 by -58, we calculate:
\[ 4 \times (-58) = -232 \]
Now, to express -232 as a mixed number in simplest form, we note that -232 is already a whole number, so as a mixed number it would be:
\[ -232 \frac{0}{1} \]
Since it's just a whole number and does not need a fractional part, the best representation in this context could be just -232. However, none of the provided options correspond directly to -232.
Thus, -232 is not given in the responses. However, since it appears there may be confusion regarding the provided options, it is worth noting that options such as -248 or any negative fractions are incorrect.
