Final answer:
The grandmother in Elizabeth Bishop's 'Sestina' is described as predictable so the correct option will be Option B.
Step-by-step explanation:
In Elizabeth Bishop's poem 'Sestina,' the grandmother is described as predictable. This can be seen in the lines 'Sylvy, Sylvy! called the busy old grandmother again and again, but nobody answered' which suggests that the grandmother is used to having Sylvy around and expects her to respond. Additionally, the fact that the grandmother and the sportsman question her about the dead hemlock tree by the green marsh shows that she is inquisitive and wants to know more. Overall, the grandmother's character is portrayed as reliable and predictable.
