Question

american roots: from native traditions to the american revolution
read the quotation from henry david thoreaus walden.
once it chanced that i stood in the very abutment of a rainbows arch, which filled the lower stratum of the atmosphere, tinging the grass and leaves around, and dazzling me as if i looked through colored crystal. it was a lake of rainbow light, in which, for a short while, i lived like a dolphin. if it had lasted longer it might have tinged my employments and life
which is the best example of a vivid sensory detail?
\once it chanced that i stood\
\if it had lasted longer\
\which, for a short while\
\it was a lake of rainbow light\

Explanation:

Sensory details appeal to the senses of sight, sound, smell, taste, or touch. "It was a lake of rainbow light" creates a vivid visual image, appealing to the sense of sight. The other options are more general statements without strong sensory - evoking elements.

Answer:

"It was a lake of rainbow light"
