Answer:

Shall

Note:In modern English will is preferred to shall. Shall is mainly used with I and we to make an offer or suggestion, or to ask for advice (see examples above). With the other persons (you, he, she, they) shall is only used in literary or poetic situations, e.g. "With rings on her fingers and bells on her toes, She shall have music wherever she goes."
