Choose the correct statement.

Options

  1. AA p -type semiconductor is positively charge(d)
  2. BThe Boolean expression 1 0=0 .
  3. CThe majority carrier in n -type semiconductor is hole.
  4. DA transistor cannot be used as a switch.

Correct answer

B. The Boolean expression 1 0=0 .

Step-by-step solution

As per Boolean postulates, aligned 1 A &=A 1 1=1 and 1 0 &=0 aligned p -type semiconductor is electrically neutral. The majority charge carriers in n -type semiconductor are electrons. A transistor can be used as a switch.
