The correct answer is: a) Paldi Bus Stand.
Paldi Bus Stand is the main bus terminal in Ahmedabad, Gujarat, India. It is located in the Paldi area of the city, and is one of the busiest bus terminals in the country. The terminal is operated by the Gujarat State Road Transport Corporation (GSRTC), and serves as a hub for inter-city and intra-city bus services.
The terminal has a large number of bus bays, and is equipped with facilities such as waiting rooms, restrooms, food stalls, and ATMs. It is also connected to the Ahmedabad Metro, making it easily accessible from all parts of the city.
The other options are incorrect because:
- Gita Mandir Terminal is a bus terminal located in the Gita Mandir area of Ahmedabad. It is a smaller terminal than Paldi Bus Stand, and serves as a hub for local bus services.
- RTO Circle is a traffic circle located in the RTO area of Ahmedabad. It is not a bus terminal, and does not serve as a hub for bus services.
- Sardar Patel Bhavan is a government building located in the Shahibaug area of Ahmedabad. It is not a bus terminal, and does not serve as a hub for bus services.
