The best answer would've been stay where she is. Because is you read carefully, she had already looked to her right side but she only saw sand. Just after a minute otrtwo, a lake can't appear there. It was a MIRAGE...

So the answer chosen by 8 users is Wrong.

And Thewellversedfangirl well done. You are right.

Seohyun wandered and wandered towards her destination which was supposedly the lake. But as she walked closer to the water body it seemed as the lake took a step forward too.

Her body required moisture and was in a desperate need of Water. Her, sweating profusely in the hot weather didn't help her situation as well.

Seohyun was not able to extinguish her thrist and even after walking for like eternity, she did not see a single drop if water.

She tried to use telekinesis and contact the rest 17 but it was of no use. She was weak and it drained her to use magic without her pendant.

Her mind couldn't function properly.

Not after long it seemed to her as the world was started spinning. Her throat was begging for water, even a single sip would do but she wanted something to drink.

The black spots were now visible in her eye sight and she knew she was going to faint.

Seohyun: Minho, why did you leave me there? 

With that Seohyun fainted on the sand.

Guys.... Read every chapter carefully...

If the majority was in favor of other option which was to stay where she was.

Seohyun would not faint
She could try and contact others or at least reply to them which would help them in finding her.  

How could 8 people go wrong at once?
