Read the excerpt from iqbal.

iqbal was released from the tomb three days later. when we saw him walk across the courtyard on wobbly legs, blinded by the light, his arms covered with angry insect bites, we pitied him, but we were proud, too.

the descriptive details in this excerpt suggest that the story takes place somewhere that

is somewhat rustic.
is very urban.
has strong family values.
has strict cultural values.

Based on the excerpt provided above, the story took place in a rural area or in a place that is somewhat rustic. The place is highly likely not a well developed area. It could be a very remote place like somewhere in the countryside or the mountains. Thus, the answer to this is the first option “is somewhere rustic”. 

one context clue that me find the meaning of luxuriance was that the base word of luxuriance is luxury, so i think that luxuriance means something that is luxury, or something luxurious.
