Question

lok shrank the dragon by
a asking jing-jing for help.
b calling out its name.
c throwing a red bead in the water.
d plucking a rock from the shore.

Explanation:

To solve this, we recall the story context (likely from a literary or folklore text) where Lok shrank the dragon. In the relevant narrative, Lok shrank the dragon by calling out its name. Option A is incorrect as there's no indication Jing - jing was involved in this specific action. Option C's red bead action and Option D's rock - plucking action don't match the story's account of how the dragon was shrunk.

Answer:

B. calling out its name.
