Options B and C are the correct options.

The expression representing the exponential growth written in the form f(x) = a ( 1+ r)^{x}, where a is the initial amount, r is the growth rate, and x is the number of time intervals.

a = 156,000, r = 0.12, x = t.

Plugging in the known values, the expression becomes.

156,000 ( 1+ 0.12)^{t} , and this can also be written as,

156,000(1.12)^{t}.

So, options B and C are the correct options.
