I would say a pond
Explanation:
A pond is more still than an ocean, therefore you could see your reflection better
It’s will be B because the circuit had a open or close so if that doesn’t work than it’s because it’s open
Let t = Theta and p = Phi
Tan t = y/x Then x =y/Tant.
Tant = y/(x-d) x-d = y/Tanp
y/Tant - d = y/Tanp
y -d*Tanr = y*Tant/Tanp
y-y*Tant/Tanp = d*Tanr
y(1 - Tanr/Tanp = d*Tant
y = d*Tant/(1-Tant/Tanp)
