Would it not be three?

Explanation:

You gots....

H_3C-CH_2CH_2CH(OH)CH_3 stackrel(H^+)rarrC_5H_10+H_2OH3CCH2CH2CH(OH)CH3H+C5H10+H2O

So (i), you might have small quantities of the C1C1 olefin...

H_3C-CH_2CH_2CH=CH_2H3CCH2CH2CH=CH2

And (ii), you might have the C2C2 olefin...

H_3C-CH_2CH=CH-CH_3H3CCH2CH=CHCH3...but EE and ZZ isomers of this olefin are conceivable...so that is three isomers in total....
