Answer and explanation

Correct answer B

Section 61(1) allows a person interested to oppose an application for restoration on two grounds only: "that the failure to pay the renewal fee was not unintentional", or "that there has been undue delay in the making of the application". A high price and non-patentability under section 3 are not grounds in restoration proceedings; they belong to compulsory licensing and revocation.
