Select the correct statement/s with respect to mechanism of sex determination in Grasshopper.
(A) It is an example of female heterogamety.
(B) Male produces two different types of gametes either with or without $\mathrm{X}$ chromosome.
(C) Total number of chromosomes (autosomes and sex chromosomes) is same in both males and females.
(D) All eggs bear an additional $\mathrm{X}$ chromosome besides the autosomes.
Choose the correct answer from the options given below :
$(A)$ only
$(A)$ and $(C)$ only
