Correct answer: B — Its acidic functional monomers condition enamel and dentine, allowing use without separate tooth etching, priming or bonding.
Explanation lettering: C = shown as A · A = shown as B · D = shown as C · B = shown as D
A is correct. Self-adhesive resin cements contain acidic functional monomers that condition and interact with enamel and dentine, so a separate tooth-etching, priming and bonding sequence is not routinely required. They therefore differ from conventional adhesive resin-cement systems that require a separate adhesive protocol. They do not require a dentine bonding agent or mandatory phosphoric-acid etching, excluding B and C. “Self-adhesive” refers principally to interaction with tooth tissue; the restoration’s fitting surface may still require substrate-specific treatment such as ceramic etching, silanisation or zirconia conditioning, so D is false. Enamel bonding may be weaker than with multistep systems unless selective enamel etching is used, making E incorrect.
