Answer:
C. 14.4 kwhr.
Explanation:
To calculate the energy used by appliance first calculate the power. The formulae for calculating power(<em>P</em>) is 
, where V stands for voltage and I stands for current.
In the given problem, V = 240 volts and I = 15 amp. Therefore,
Now, formulae for calculating energy used i.e. work(W) is 
, where <em>t</em> is the time.
In the given question time is 4 hr. Therefore energy used will be,
Energy used (W) = 
.
