Having unearthed the remains of the woman who presumably sat for La Monalisa, archaeologists now hope that by means of facial technology reconstruction, it will be possible to put a name to da Vinci's enigmatic muse.

a) Having unearthed the remains of the woman who presumably sat for La Monalisa, archaeologists now hope that by means of facial technology reconstruction, it will be possible --- Correct

b) The archaeologists who unearthed the remains of the woman now hope that the facial reconstruction of La Monalisa will make it possible --- who sat for Monalisa, is missing. A fatal change in the meaning. ‘The woman’ lacks proper definition.

c) A group of archaeologists has unearthed the remains of the woman that is believed to have sat for La Monalisa, now hoping that by means of facial technology reconstruction, it may be possible –--- ‘woman that’ is unidiomatic. In addition, the logic is faulty, as it looks as though the group has unearthed something just as it is hoping simultaneously. The unearthing is first and the hoping is later

d) Archaeologists, having unearthed the remains of the woman who presumably sat for La Monalisa, are now hoping that it will be possible with facial technology reconstruction --- A very subtle wrong word order. “What will be possible?” – it is possible “to put a name”. both these should go next to next.

e) Having unearthed the remains of the woman who could have possibly sat for La Monalisa, now a group of archaeologists was likely, by means of facial technology reconstruction --- ‘was likely’ is wrong tense; in addition, the hope of the group is totally missing.
