    某色谱柱子上,苯和奈的保留时间和半峰宽分别为4.65和7.39 min、0.158和0.228 min;求柱效果和分离度。
    A: n(苯)=4.80x10^3 /m, n(萘)=5.82x10^3 /m, R=8.36
    B: n(苯)=3.80x10^3 /m, n(萘)=4.80x10^3 /m, R=6.26
    C: n(苯)=4.00x10^3 /m, n(萘)=5.00x10^3 /m, R=8.36
    D: n(苯)=4.50x10^3 /m, n(萘)=5.23x10^3 /m, R=4.36
    E: n(苯)=2.80x10^3 /m, n(萘)=5.35x10^3 /m, R=6.86
