According to the accounts of Ibn Batutta, what was 'uluq'?

Horse-post

The correct answer is Option 2 - Horse-post

Ibn Batutta described the India postal system as very efficient. This is how Ibn Battuta describes the postal system: In India the postal system is of two kinds. The horsepost, called uluq, is run by royal horses stationed at a distance of every four miles. The foot-post has three stations per mile; it is called dawa, that is one-third of a mile ... Now, at every third of a mile there is a wellpopulated village, outside which are three pavilions in which sit men with girded loins ready to start. Each of them carries a rod, two cubits in length, with copper bells at the top.
