Which of the following statements is/are correct ?

I. Pure Si doped with trivalent impurities gives a p-type semiconductor
II. Majority carriers in a n-type semiconductor are holes
III. Minority carriers in a p-type semiconductor are electrons
IV. The resistance of intrinsic semiconductor decreases with increase of temperature

I, III and IV

The majority charge carrier in n-type semiconductor is electrons (negative (n)) and in p-type semiconductor majority charge carrier are holes (Positive charge(P)).
