To add the fractions \( \frac{12}{1} + \frac{38}{1} \), we just add the numerators since the denominators are the same (both are 1):
\[ \frac{12 + 38}{1} = \frac{50}{1} = 50 \]
None of the provided options directly match the sum of \( 50 \). However, if you were looking for a different operation, or if there was a misunderstanding in the formatting of the question, please clarify!
