Correct Answer
C. Cannot modify the source code for profitExplanation
Linux is an open-source operating system, which means that its source code is freely available and can be modified by anyone. However, the answer states that Linux cannot modify the source code for profit. This is because the GNU General Public License (GPL), which governs Linux, requires that any modifications made to the source code must be made freely available to others. Therefore, while individuals can modify the source code for personal use or non-profit purposes, they cannot do so with the intention of making a profit from it.Rate this question:
