Assume a program has the following variable definitions:

int units;

float mass;

double weight;

and the following statement

weight = mass * units;

Which automatic data type conversion will take place?

a) mass is demoted to an int, units remains an int, and the result of mass * units is an int.

b) units is promoted to a float, mass remains a float and the result of mass * units is a float.

c) units is promoted to a float, mass remains a float and the result of mass * units is a double.

Idon understand these and need some ! ?
