The correct option is B Pteridophyta
Thallophytes do not have well-differentiated plant body and vascular tissues. Therefore, option A is incorrect.
Bryophytes have well-differentiated plant body with stem and leaf-like structures. But there is no specialized vascular or mechanical tissue. Therefore, option B is incorrect.
Fungi are heterotrophic, eukaryotic organisms. Fungi are unable to make their own food material. Fungi do not possess specialized tissue for water conduction. Therefore, option D is incorrect.
Pteridophytes have well-differentiated plant body with vascular tissues. Therefore, option C is correct.
