Explanation:

The early Solar System started as a nebula (a large cloud of gas and dust). As gravity caused it to collapse, it spun faster and flattened into a disk - like shape while also becoming smaller in terms of the concentrated mass (though the overall spread was changing in structure). The option "the shape did not change" is incorrect as the nebula transformed. "It exploded" is wrong as the Solar System formed via collapse, not explosion. "It became larger and round" is incorrect because the collapse made it smaller and flatter, not larger and round. So the correct option is the one stating it became smaller and flatter.

Answer:

It became smaller and flatter
