Respuesta :
"Jennings was uncomfortable with having to send strong warnings to Germany against their indiscriminate submarine warfare" was the immediate reason that caused US Secretary of State William Jennings Bryan to resign in June 1915. The correct option among all the options that are given in the question is option "d".
I believe the answer is: d. Jennings was uncomfortable with having to send strong warnings to Germany against their indiscriminate submarine warfare.
Jennings feared that by sending strong warnings to Germany, United States' citizens would become the new main target of the attack which could lead to million of death. Not wanting to be held responsible for that, Jennings choose to resign instead.
