Does it make sense?
“ So what have you been getting ... while i’ve been.”
A down to
B away with 
C up to
D through to
Option C is the key. But I don’t understand. Is it a question or just a sentence? What is the meaning and the grammar structure????

“ So what have you been getting up to while I’ve been away ? ”
- to 'get up to something' means to do something - it's familiar and friendly.
It's usually used as a question to someone you know well.

There is another colloquial phrasal verb expression 'get down to' , which means to work on something -
'When are you going to get down to doing that job ?'
'When is he going to get down to work ?'
'They arrived there and got straight down to work.'
'Let's get (straight) down to business.'
To get straight down to something means to do it immediately /right away.

It's not complete as it is - you need something else at the end, for example:

"So, what have you been getting up to while I've been working?"

It's a question asking what the other person has been doing while you've been doing something, but it doesn't make sense as it is.

"Getting up to" - means "what have you been doing"
You could also use "Getting away with" - but that has a different meaning.
