Which of the following statements i s/are correct with regard to Milky Way? 1. It is a spiral gal axy. 2. The solar system resides in one of its spiral arms. Select the correct, answer using the code given below :

The Milky Way is classified as a large, disc-shaped spiral galaxy [2]. Specifically, modern astronomical data identifies it as a barred spiral galaxy, characterized by a central bar-shaped structure and a pinwheel-like appearance when viewed from above. The galaxy contains several spiral arms consisting of stars, gas, and dust [1]. The Solar System is located within the Orion Arm, also frequently referred to as the Orion Spur or Local Arm [2]. This arm is situated approximately 25,000 to 26,000 light-years from the galactic center, placing our solar system about one-third of the way toward the edge of the galaxy [1]. While some debate exists regarding whether the Orion Arm is a major arm or a minor spur, it is universally recognized as the spiral structure containing our Sun. Therefore, both statements are correct.
