Question about tenses

Which is correct, and why?

A. The phone rang while I was having a path

B. The phone was ringing while I was having a path

Correct letter A. Sounds more efficient than the letter B also it's used in past tense

A

Explanation:

A uses a past tense (rang) which is correct for a past tensed sentence

Mean while B uses a present tense (ringing) for a sentence which is past tensed, which makes no sense and is absolute non sense.
