In his rise to power, Julius Caesar accomplished several things, but among the options provided, the most accurate response would be:
He created public works programs and jobs for the unemployed.
Caesar did implement a number of reforms aimed at addressing social issues, including public works projects that provided employment for the lower classes. While he made significant changes that paved the way for the decline of the Roman Republic and the rise of imperial rule, he did not outright change the Republic into a monarchy during his lifetime, nor did he establish a civil service as we understand it today. Giving public lands to the wealthy doesn't align with his known reforms either, as he often aimed to redistribute land to the veterans and lower classes.
