💡 Solution & Explanation

Step 1: Concentrated nitric acid (HNO3) is a strong oxidizing agent and oxidizes non-metals to their corresponding highest stable oxyacids. Step 2: When reacted with iodine (I2), nitric acid oxidizes it to iodic acid (HIO3 or HOIO2), while being reduced to nitrogen dioxide (NO2). Step 3: The balanced equation is: I2 + 10HNO3 -> 2HIO3 + 10NO2 + 4H2O. Since HOIO2 represents iodic acid, option (c) is the correct answer.
