Correct answer is C:

Calculated Load [see 220.40]
General Lighting Load: 1500 sq ft at 3 VA per sq ft = 4500 VA
Minimum Number of Branch Circuits Required [see 210.11(A)]
General Lighting Load: 4500 VA ÷ 120 V = 37.5 A
This requires three 15-A, 2-wire or two 20-A, 2-wire circuits.
Small Appliance Load: Two 2-wire, 20-A circuits [see210.11(C)(1)]
Laundry Load: One 2-wire, 20-A circuit [see210.11(C)(2)]
Bathroom Branch Circuit: One 2-wire, 20-A circuit (no additional load calculation is required for this circuit) [see210.11(C)(3)]
Minimum Size Feeder Required [see 220.40]

General Lighting        4,500 VA 
Small Appliance        3,000 VA 
Laundry       1,500 VA 
Total     9,000 VA 
3000 VA at 100%     3,000 VA 
9000 VA – 3000 VA = 6000 VA at 35%     2,100 VA 
Net Load     5,100 VA 
Range (see Table 220.19)     8,000 VA 
Dryer Load (see Table 220.54 )    5,500 VA 
Net Calculated Load    18,600 VA
