Answer is E.
1) Tells us the number of employees, but nothing about their income (Not Sufficient)
2) Tells us the income of 12 of the 29 employees, however, we know nothing about the remaining 17 employees' income. (Not Sufficient)
1) & 2) Together: Not sufficient, as given that there are 29 employees, we would need to know where the 12 employees earning $24,000 lie in the spread of the income distribution.

We need the median annual salary.
Statement 1 gives us the number of employees. Without the annual salary of the 15th employee, we cannot answer the question. Statement 1 is insufficient.
Statement 2 gives us the annual salary of 12 employees. We don't know how many employees had the company last year, so statement 2 is insufficient.
The two statements together are still insufficient to answer the question. We know that we need to find the annual salary of the 15th employee but the we don't know if one of the 12 employees mentioned in the second statement was the one that had the median value.
The correct answer is E.
