Answer: B
Explanation:
It only became runny because it was so hot outside.
Why the others are wrong:
A. it only became runny consequently it was so hot outside. "Consequently" means as a result, but in this context (the way it is being used), the sentence is essentially saying, "It only became runny and as a result, it was hot outside". That's not what the writer is trying to say.
C. Using "during" in this context is bad english and makes no sense. "It only became runny during it was so hot outside"
D. No sense and bad english
health is wealth and we shouldnot use tobacco and other drugs .
If read from the context, the word amiability would mean joviality, so Answer B would be correct.
