C)The gas in the solar nebula would create a drag on the planets and their orbits would migrate inwards.

A strong wind from the central star helps to remove any excess gas and dust from the solar nebula, allowing planets to continue to grow through accretion without migrating inwards. Without this wind, the planets would experience drag from the gas in the nebula, causing their orbits to migrate inward over time.
