Which of the following formula correctly defines natality?

(a) Natality = \frac{Number \, of \, deaths \, per \, year}{Mid-year \, population}
x 1000

(b) Natality = \frac{Number \, of \, births \, per \, year}{Mid-year \, population}
x 1000

(c) Natality = \frac{Number \, of \, births + Number \, of \, deaths}{Mid-year \, population}

I have been asked this question in quiz.

The origin of the question is Population Growth in chapter Organisms and Populations of Biology – Class 12
