Because secondary alcohols are smaller and therefore less reactive for the attack of halide nucleophile. Because tertiary alcohols have more hydrogen atoms available for substitution reactions. Because a tertiary alcohol can form a more stable carbocation as an intermediate in the reaction. Only the 1st and the 2nd statements are acceptable.
