Hey there, Bulgogi!
The correct answer will be the first one since [I'm assuming] you know that to calculate the percentage of something, it's the amount of that something divided by the total amount but since only 30 students voted [12+18] multiplied by 100.
So, we are calculating the percentage on votes and 12 students voted for Candidate A so our Numerator will be 12 and our Denominator will be the total amount of student who voted, so 30 [or 12+18]
Once put into a fraction, we will get

which would be equals to 2/5 or 0.4. Now we multiply by 100 and we get a total of 40% for Candidate A.
Thank you for using Brainly.

Step-by-step explanation:
We have the expression, 
We get, eliminating the cosecant function,

As, sinx is reciprocal of cosecx and cosx is reciprocal of secx,
i.e. 
i.e. 
Since, we know that, 
Thus,

So, after simplifying, we get that the result is 1.
Hence, option D is correct.
