○　正解です。

When someone sneezes the correct response is 'Bless you' or 'God bless you'.
'Take care' or 'Get well soon' are used when somebody is sick.
For example :
'How are you?'
'Not so good. I have a cold'
'I'm sorry to hear that. Get well soon.' (又は'Take care')

Saying 'Bless you' or 'God bless you' (神の加護を祈る) when somebody sneezed became popular during the bubonic plague (ﾍﾟｽﾄ). The Pope ordered people to say 'God bless you' to stop the plague.
