A．奇數(shù)

B．偶數(shù)

C．都有可能

Answer 1

分析：根據(jù)奇數(shù)與偶數(shù)的意義，是2的倍數(shù)的數(shù)叫做偶數(shù)，不是2的倍數(shù)的數(shù)叫做奇數(shù)；奇數(shù)×奇數(shù)=奇數(shù)；偶數(shù)×偶數(shù)=偶數(shù)；奇數(shù)×偶數(shù)=偶數(shù)；據(jù)出解答．

解答：解：奇數(shù)×偶數(shù)=偶數(shù)；
答：一個奇數(shù)和一個偶數(shù)的積是偶數(shù)．
故選：B．

點評：此題考查的目的是使學生理解和掌握偶數(shù)與奇數(shù)的意義．
