Hey,

As you have not studied political science (because you have not mentioned the subject marks) so you can take any four subject from the above mentioned.

Although as you are not including the political science marks and you wish to apply for political science (BA) , a penalty of 2.5% will be deducted from your best of four marks.

Above I have attached a link that contains the eligibility along with the percentage calculation before applying for courses.

Hope that helps.

Thank you.
