If you could find the coldest object on earth, you would find that it
a. contains no heat
b. has some thermal energy
c. has a temperature of absolute zero
d. would be emitting cold into the environment

B. Has some thermal energy. A and B both refer to absolute zero, which is nearly impossible to reach on earth or elsewhere. D is incorrect because it's impossible to emit cold, since cold isn't a form of energy (rather, it's just the absence of heat).
