How to take row header from CSV file

Question

Okay so i have to read data from an CSV file and add methods that calculate which is seen in my code below, so my question is how can i put in output the header of a row (example first,second or third) from which the value has been taken from?

Possibilites | first | second | third| fourth
Decrease     |  28   | 24     | 16   |  25
Increase     |  30   | 42     | 44   |  45

this is a CSV file im using

My output is like this:

Optimist: first  (45)
Pessimist: second  (30)
Laplace:  third(33)
Least regret:  fourth(5)

But i want it to be like this:

Optimist: fourth (45)
Pessimist: first(30)
Laplace:  second (33)
Least regret:  fourth(5)
