Explanation: Fine Arts Course থাকলে, English or Social Studies Course থাকতে পারবে না। Science Course থাকলে অবশ্যই Maths Course থাকতে হবে। যদি শিক্ষার্থী একটি বিজ্ঞান কোর্স নিতে চায়, তাহলে তাকে অবশ্যই একটি গণিত কোর্সও নিতে হবে। তাকে তিনটি কোর্স নিতে হবে এবং কমপক্ষে দুটি ভিন্ন ক্ষেত্র থেকে কোর্স নিতে হবে। সে ইতিমধ্যে একটি বিজ্ঞান কোর্স (১ম কোর্স) এবং একটি গণিত কোর্স (২য় কোর্স) নিচ্ছে, তার আর একটি কোর্স বাকি থাকে। Option A: একটি গণিত কোর্স এবং একটি সামাজিক বিজ্ঞান কোর্স। সে ইতিমধ্যে একটি গণিত কোর্স নিয়েছে, তাই অতিরিক্ত আরেকটি গণিত কোর্স নেওয়া সম্ভব (মোট: Math, Science, Math, Social Studies, which is 4 courses). Wait, the pair must *complete* the schedule to 3 courses. So he takes Science + (pair). The pair in A is (One math course & one social studies course). So, total courses: Science, Math, Social Studies. This is acceptable. Option B (Two science courses) means total: Science, Science, Science, which is only one area, violating the 'at least two different areas' rule. Option C (Two English courses) means total: Science, English, English (Math is missing for Science). Also, 2 English courses are not a pair for a single remaining slot. The question is flawed or I misunderstood 'pair of course'. Assuming the 'pair' are the two *remaining* courses, total courses are Science + Math + Social Studies. This satisfies all rules. Hence A is correct.
