Which one of the following can one come across if one travels through the Strait of Malacca ?

The Strait of Malacca is the narrow sea corridor running between the Malay Peninsula and the Indonesian island of Sumatra; it is commonly mentioned together with the adjacent Singapore Strait and is a principal approach to the port city-state of Singapore, which lies at the southern tip of the Malacca/Singapore maritime route [1]. Therefore, a vessel transiting the Strait of Malacca would commonly encounter Singapore. By contrast, Bali and Java lie farther southeast of Sumatra in the Indonesian archipelago and are not located in the Malacca channel, while Brunei is on the island of Borneo well to the northeast—none of these lie on the Malacca–Singapore route in the same way as Singapore does.
