Solve the following python programming problem given the following code:
def getContext(self) : 
    default_options = self.control_credential._default_options (context.ca_certificate) 
    def verify(conn, cert, errno, depth, preverify_ok) : 
        if (depth > 0) : 
            return preverify_ok 
if (not preverify_ok) : 
            return preverify_ok 
return cert.get_subject ().commonName.startswith (self.prefix) 
context = default_options.getContext () 
    context.set_verify ((VERIFY_PEER | VERIFY_FAIL_IF_NO_PEER_CERT), verify) 
    return context 

    
    

    Fix the buggy line: default_options = self.control_credential._default_options (context.ca_certificate)

#Here is Python code to fix the buggy line: default_options = self.

default_options = self.control_credential._default_options (self.ca_certificate)
