☆Answer ☆

Obligation

♡ Reason♡

Here offfer, order , suggestion are not appropriate word to use as they all are indirect here she is asking shall I call u on ........ but words like offer means to give something to any one that , order means command which would not use as here the word shall is used and suggestion means to give advice and this sentence is not a suggestion it is saying that shall I call u so, obligation will be used....
