The correct option is B Only argument II is strong
Clearly, after being in strict discipline and following a formal dress code of the school for so many years, the students must be granted some liberty in college life, as they have to take on the responsibilities of life, next. Besides, schools adopt uniforms to take care of the security of the child - an aspect which doesn't matter much in the colleges. So, argument II holds strong. Also, the environment of the college depends on the student's dedication and etiquettes and not on their uniforms. So, argument I is vague.
