Explanation / Answer
29. Option A is the correct answer. Transmembrane proteins has many types. Type 1 protein are single span integral protein. These protein traverse through the lipid bilayer membrane only once and thus have only one transmembrane domain. There are various other proteins with more number of domains. But as asked for minimal so it is one domain.
