I shall satiate my ardent curiosity with the sight of a part of the world never before visited, and may tread a land never before imprinted by the foot of man. These are my enticements, and they are sufficient to conquer all fear of danger or death and to induce me to commence this laborious voyage with the joy a child feels when he embarks in a little boat, with his holiday mates, on an expedition of discovery up his native river.

In context, the phrase “sufficient to conquer all fear of danger” most nearly means

(A) capable of making me courageous
(B) barely enough to get me through the fear
(C) too effective to prevent fear
(D) not enough to defeat the fear
