b. because of his family

Explanation:

Pablo Neruda never wanted to clarify that of his new identity as Pablo Neruda, who adopted being almost a child, as a poetic name. Many times they asked him the origin of this form of "surname", and he used to answer with evasions, leaving the case even more tangled. There are several stories - or better let's call them hypotheses - about it. It has been said, not once, but hundreds, that he himself took the name of the Czech writer Jan Neruda, beset by the need to mask his own identity in the face of the phobia that his father had for poets and writers. Don José del Carmen Reyes Morales, peasant first, railway worker later, man of few reasons, did not want to have an "artist in the family; that never". However, the concrete thing is that when the young Eliecer Neftalí Reyes Basoalto began to self-identify Pablo Neruda, back in the late 1920s, he did not even know the existence of the Czech writer Jan Neruda, who is said to have taken his surname. From here the doubts begin and the speculations are born on such a big topic.
