Option 2 : 14%

According to the question, let the following Venn diagram,

Now, 

e = 5%

b + e = 14%

⇒ b = 9%

and,

d + e = 18%

⇒ d = 13%

Therefore, 

Percentage of students who failed only in Economics = a = 41% - (b + e + d)

a = 41% - (9 + 5 + 13)%

a = 41% - 27%

a = 14%

Hence, 14% is the correct answer.
