a) all b) each c) every d) both
The model answer is both, but I wonder if 'each' is also a possible answer.
Yes, "each" is also a possible answer. The model answer should reflect this.
Whether you use "each" or "both," do not set the word off by commas.
The following answers are both perfectly correct:
(b) My parents each have a mobile phone.
(d) My parents both have a mobile phone.
Please note that if you use the related partitive construction with "each," the verb will need to be singular.
(e) Each of my parents has a mobile phone.
(f) Both (of) my parents have a mobile phone.
