Which of the following statements is not true?

A The resistance of intrinsic semiconductor decreases with the increase of temperature
B Doping pure Si with trivalent impurities gives p-type semiconductors
C The majority carriers in n-type semiconductors are holes
D A p-n junction can act as a semiconductor diode
