The correct answer is number 3) they were nomadic.
What describes how the ancient Israelites were similar to the early Aryans was that they were nomadic.
Indeed, since Biblical times, the Israelites had been a race that has been persecuted for many reasons and had to roam through many places, considering them as nomads. For example, the Book of Exodus in the Old Testament refers to Moses and how he led the Israelites to the Promise Land in a trip that took 40 years, wandering through the desert.
