Most probably it is an OG question.
IMO D.
"visible" modifying equipment, as "obtrusive" is modifying equipment in underlined part.
"overestimate the amount of energy" parallels "underestimate that".

E is wrong because of unnecessary use of "when".

OA is D

Lacking information about energy use, people tend to overestimate the amount of energy used by equipment, such as lights, that are visible and must be turned on and off and underestimate that used by unobtrusive equipment, such as water heaters.

A. equipment, such as lights, that are visible and must be turned on and off and underestimate that
>>>SV agreement error

B. equipment, such as lights, that are visible andmust be turned on and off and underestimate it when
>>>same as A

C. equipment, such as lights, that is visible andmust be turned on and off and underestimate it when
B. equipment, such as lights, that are visible andmust be turned on and off and underestimate it when
E. visible equipment, such as lights, that must be turned on and off and underestimate it when
>>>the use of "when" suggests people are used by equipment

D. visible equipment, such as lights, that must beturned on and off and underestimate that
>>>people tend to overestimate the amount of energy used by visible equipment, such as lights, that must beturned on and off and underestimate that used by unobtrusive equipment, such as water heaters.
simplify
people tend to overestimate the amount of energy used by X and underestimate that used by Y
that -refers to the amount of energy =>IIlism is intact

Wow good explaination but I had hard time to believe that second that actually refers to the amount of energy.

On another note, what does it refers to in the E?

IMHO
"it" in E is ambiguous.
It should actually refer to amount of energy but it can also refer to equipment.
