An alcohol of unknown structure gave a positive Lucas test in about five minutes. When alcohol was heated with concentrated `H_(2)SO_(4)` an alkene was formed with the formula `C_(4)H_(8)`. Ozonolysis of this alkene gave a single product, `C_(2)H_(4)O`. What was the structure of the alcohol ?

A

butan-1-ol

B

butan-2-ol

C

2-methylpropan-1-ol

D

2,2-dimethylbutan-1-ol
