Answer's in the question. '30% of employees who are not vulnerable to the infection are more than or equal to 17 years of age.'
30%>24%. Therefore, A.
That's the only way I could interpret this.
Question's a bit incomprehensible. If option A, by 'percent employees', refers to the percentage from the total number of employees, then the answer is C.

Explanation:
Refer to the table;
Let the total number of employees be 100
Vulnerable employees be M
So, Not vulnerable = (100 - M)
Now,
We are given that 0.8M = 16% of T
i.e. M (vulnerable employees) = 20 and,
100 - M (Not vulnerable employees) = 80
Therefore, number of employees who are vulnerable and are less than 17 years old = 0.2(20) = 4
Complete rest of the table.
Col. A: \(\frac{24}{40} = 60\)%
Col. B: \(24\)%
Hence, option A
