Answer:
B). They represent something great.
Step-by-step explanation:
The words, 'morning' in "Will there really be a 'Morning?" and 'possibility' in "I dwell in Possibility" are common as both of them represent something 'great' as the former poem employs 'morning' as a metaphor of 'Christ' while the 'possibility' in the latter stands for the poet's 'strength/power gained' through poetry. Both the poems by Emily Dickinson are dealing with great subjects. Thus, option B is the correct answer.
