Newton's first law of motion states that an object at rest stays at rest unless acted upon by a force while an object at motion stays in motion unless acted upon by an opposite force. Therefore, the ball in motion will stay at motion considering there is no friction force in the field, answer is A. If the field has friction force against the ball then it will slow down and stop eventually, answer is B.

Newton's simply states a body would continue in its state of rest or of uniform motion unless it is acted upon by a force.

So if you roll this ball in the open field, and I presume this open field is the one we have on the Earth.

Like we both know frictional forces would oppose the ball, and finally the ball will slow down and finally come to rest.

Option B is the best answer.
