Jorge Marie Bergoglio was ordained priest in the new rite in 1969; he was consecrated a bishop in the new rite of consecration in 1992.
Per Canon Law - if the man elected is not a priest or a bishop he is to be ordained, consecrated or both by the Dean of the Sacred College.
The man elected to the papacy will assume the Bishopric of Rome. Therefore, he must be a bishop - if not before his election, then immediately following it.
A negative doubt is to be despised and is really no doubt at all.
If you only have negative doubts about the new rite(s) of ordination and/or consecration - then you really have no doubt at all and therefore you can have no doubt that Francis is both a priest and a bishop.
On the other hand...
One is not permitted to have positive/probable doubts concerning the validity of Sacraments received/conferred.
If he is a doubtful priest, he is a doubtful bishop,
If he is doubtful bishop, then he has doubtfully fulfilled the criteria necessary to assume the Bishopric of the Roman See.
While the man elected pope upon his acceptance, immediately assumes full and supreme jurisdiction - were all his acts are valid,
in such a case study as those who entertain doubts over the new rites of ordination/consecration, but still hold him to be the pope, these validity-of-Jorge's-orders-doubters, would in effect, be holding that a man can be a valid pope without being the Bishop of Rome - or at least doubtfully being the Bishop of Rome.
Therefore Option 7 [He is doubtfully the bishop of Rome, but he is still the pope.] is what you really believe.
Can the pope be just a layman and not hold the Bishopric of Rome?
Can the papacy be separated from the Bishopric or Rome?
Can the pope be the Chief Shepherd when he isn't even a shepherd (bishop)?
A doubtful pope is no pope. No?
