You want Series.str.get_dummies then use DataFrame.add_prefix to get your desired column names:

df['Feature'].str.get_dummies(sep=',').add_prefix('feature_')
   feature_option1  feature_option2  feature_option3  feature_option4
0                1                0                1                0
1                0                0                0                1
2                0                1                1                0
