• Saviour Sibling refers to babies that are created to serve an older sibling as a donor of organs, bone marrow or cells. 
• Stem cells from the umbilical cord blood or blood of the saviour sibling are used for treatment of serious blood disorders like Thalassemia, Sickle Cell Anaemia.
• They are created with In vitro fertilisation (IVF) so that they can undergo pre-implantation genetic diagnosis (or testing) to rule out any genetic disorders and also check bone marrow compatibility. 
• In vitro comes from the latin word ‘in glass’, i.e. studies are done in a test tube rather than in a human or animal.
• The opposite to ‘In-vitro’ is ‘In-vivo’, which comes from the latin word ‘within the living’. In vivo refers to experimentation being done in a living organism.

Hence only statement 1st is correct.
