Which one among the following places is situated close to the Pearl River Estuary in Asia ?

The Pearl River (Zhujiang) Estuary is located in southern China, where the Pearl River system discharges into the South China Sea [1]. The estuary is approximately 29 km wide, with Hong Kong situated to its east and Macau situated to its west [2]. While both cities are integral to the Pearl River Delta region, Macau is geographically positioned directly on the western side of the estuary's entrance [2]. In contrast, Bangkok is located in Thailand at the Chao Phraya River Delta, discharging into the Gulf of Thailand [3]. Singapore is an island nation located significantly further south at the tip of the Malay Peninsula. The Pearl River Delta region, often referred to as the Guangdong-Hong Kong-Macau Greater Bay Area, includes major cities like Guangzhou, Shenzhen, and Zhuhai. Among the given options, Macau is the most precisely situated at the estuary's immediate entrance.
