Statement (1) is clearly insufficient - discloses no information about the volumes thickness.
Statement (2) is not conclusive, either. It says something about some 12 of the 20 volumes encyclopedia, nothing about the FIRST 10 that will tentatively be put in the bookrack.
Thus our option would be (E) - statements, even taken together, are insufficient.
