If Meselson and sthal`s experiment is continued for four generations in bacteria, then the ratio of N15/N14 : N14/N14 containing DNA in fourth generation would be 1) 1:3 2)1:7

If Meselson and Stahl experiment is continued for four generation the ratio of N15-N14 : N14-N14 containing DNA would contain 12.5% hybrid and 87.5% N14-N14 DNA . SO ratio comes out to be 1:7.
