1. f₁ = ∑m (1, 2, 4, 8, 10, 14)
2. f₂ = ∑m (2, 5, 9, 15)

Assertion (A): Holes are majority carriers in p type semiconductor.

Reason (R): In p type semiconductor, the electrons produced by thermal agitation recombine with holes.

Assertion (A): A demultiplexer cannot be used as a decoder

Reason (R): A multiplexer selects one of many outputs whereas a decoder selects on output corresponding to coded input.
