Answer:
{January, February, March, April, May, June, July, August, September, October, November}
Step-by-step explanation:
The set is formed by months of year with indexes larger than 0 and lesser than 12.
The year starts at month 1, which is January, and finishes at month 12, which is December.
Since we want lesser than 12, December is not part of the set. So the answer is given by:
{January, February, March, April, May, June, July, August, September, October, November}
