Agriculture is thought to have developed independently throughout the world, so there is not necessarily one particular group of people that could be considered to be the first. However, of the available options the most likley to be correct would be a) Nomads in Central Asia. The 'fertile crescent' in the East is often referred to in this respect, as being the first place agriculture was properly developed.
