1. (a) Dysentery is a type of intestinal inflamation and generally caused by Shigella bacillus bacterium. And the major possibility for spreading or transmission of this disease through contaminated water.So this option is correct.

(b) The term vehicle transmission means that the transmission of the disease occurs by vehicle for example water,air or food. But the STD (sexually transmitted disease) does not need any type of these vehicle. So STD is not an example of Vehicle transmission.So this option is incorrect.
