1. If four consecutive natural numbers are all composite, then the minimum value of the sum of these four numbers is ( ).
(A) 100
( B ) 101
( C ) 102
(D) 103
Analysis: The smallest four consecutive composite numbers are $24, 25, 26, 27$, so the minimum sum of these four numbers is $24+25+26+27=102$, hence the answer is C.
