Conclusions:
I. No introvert is an ambivert. → False (No introvert is an extrovert, all extroverts are ambiverts. So we can say that no introvert is an ambivert it can be possible but not definite, hence, false)
Il. No ambivert is an introvert. → False (No introvert is an extrovert, all extroverts are ambiverts. So we can say that no ambivert is an introvert it can be possible but not definite, hence, false)
III. Some ambiverts are extroverts. → True (All extroverts are ambiverts. So we can say that some ambiverts are extroverts as follow.)
IV. All ambiverts are extroverts. → False (All extroverts are ambiverts but all ambiverts are extroverts it does not follow.)
Hence, "option 3" is the correct answer.
