So indicative votes on C, D, E and G.
The following is the BBC'S brief summary of each:
Motion C: Customs union
Proposer: Ken Clarke, Conservative
This option commits the government to negotiating "a permanent and comprehensive UK-wide customs union with the EU" as part of any Brexit deal.
This arrangement would give the UK a closer trading relationship with the EU and reduce the need for some (but not all) checks at the Irish border.

But it would prevent the UK striking independent trade deals with other countries, and has previously been ruled out by Mrs May.
A version of this proposal received the most support in the first round, falling just six votes short of a majority.
Motion D: 'Common Market 2.0'
Proposer: Nick Boles, Conservative
This proposal would mean joining the European Free Trade Association and European Economic Area, with countries such as Norway.
It means the UK would remain part of the EU single market and would retain freedom of movement, so British citizens would keep the right to live and work in the EU and vice-versa.
In the last round, 188 MPs voted for this plan and 283 voted against.
Motion E: Confirmatory public vote
Proposers: Peter Kyle and Phil Wilson, Labour
This gives the public a vote to approve any Brexit deal passed by Parliament, before it can be implemented.
Tabled last time by Labour former minister Dame Margaret Beckett, this option won the highest number of votes, with 268 MPs for and 295 against.
Motion G: Parliamentary supremacy
Proposer: Joanna Cherry, Scottish National Party
This option offers a series of steps to prevent the UK leaving the EU without a deal. First, it requires the government to seek an extension if a deal has not been agreed two days before the deadline for leaving.
If the EU does not agree to an extension, on the day before the UK was due to leave, MPs would be asked to choose between a no-deal Brexit or revoking Article 50 to stop Brexit altogether.
In the event of revoking Article 50, an inquiry would be held to find out what type of future relationship with the EU could command majority support in the UK and be acceptable to Brussels.
MPs previously voted against a proposal to cancel Brexit by Joanna Cherry, but have not considered this plan before.
