To find the number of students in the choir, we can use the ratio given in the problem. The problem states that there are 5 students in choir for every 1 student in band.
Let \( b \) be the number of students in band, and \( c \) be the number of students in choir. According to the ratio, we have:
\[ \frac{c}{b} = 5 \]
We also know there are 58 students in band:
\[ b = 58 \]
We can substitute this value into the ratio equation:
\[ c = 5 \times b = 5 \times 58 = 290 \]
Thus, the number of students in choir is \( 290 \).
The correct answer is \( \boxed{290} \).
