Answer:
A (?)
Step-by-step explanation:
A) An open ocean has direct sunlight almost always, unless if it's night time, meaning that the surface would be open to sunlight whenever necessary. A lake also has more clean water, meaning sunlight can easily go through the water
B) A lake or a muddy river would likely also have direct access to sunlight, however, it could be covered easily by trees or other vegetation. And the mud in the river would likely make it difficult for sunlight to pass through.
C) A kelp forest likely blocks large amounts of sunlight because of their large structures and the tops usually grow outwards, meaning large amounts of sun would be covered.
D) See B and C
E) A spring is usually hidden in a forest, meaning it would possibly be difficult to collect sunlight due to the heavy vegetation and large trees that usually surround them.
This question is somewhat difficult to answer because most of these can be seen anywhere, meaning some can get sun while others can't, so it's hard to determine. Sorry if I got it wrong!
