Explanation: Distance BC বের করার জন্য, Statement 1 \((BD=10)\) থেকে আমরা পাই \(BC + CD = 10\)। Statement 2 \((AC=12)\) থেকে পাই \(AB + BC = 12\)। কোনোটি থেকেই এককভাবে BC এর মান বের করা সম্ভব না, এবং দুটি statement একসাথে ব্যবহার করেও BC এর সুনির্দিষ্ট মান বের করা যায় না কারণ AB এবং CD এর মান অজানা থেকে যায়। তাই উত্তর E হবে।
