Your answer would be A.
I hope this helps.
Its B because it was mostly about death
Answer: D. Goes – will have spent
Explanation:
From the options given, note that for the first part, "went" or "gone" can't be the correct option since the event hasn't happened yet as the sale is still forthcoming, therefore, the right word is "goes".
Therefore, the correct sentence will be:
By the time the software (goes) on sale next month, the company will have spent $2 million on developing it.
<span>B) Animals used in a Species Survival Plan are sometimes taken out of the public viewing areas for a private, less stressful area to breed and care for their offspring in the first critical weeks.
B is the best option of the ones we can see. You didn't include the sentence as is so I don't know if A is better. I do know for a fact that options C and D are grammatically incorrect. The difference in the sentences is really the use of the adjective phrase (used in a Species Survival Plan). This phrase clarifies which animals are moved out of viewing areas.
