Which excerpt from John Muir’s "Save the Redwoods" best appeals to readers’ logic?

a. Could one of these Sequoia Kings come to town in all its godlike majesty so as to be strikingly seen and allowed to plead its own cause, there would never again be any lack of defenders.

b. Forty-seven years ago one of these Calaveras King Sequoias was laboriously cut down, that the stump might be had for a dancing-floor. Another, one of the finest in the grove, more than three hundred feet high, was skinned alive to a height of one hundred and sixteen feet from the ground and the bark sent to London to show how fine and big that Calaveras tree was—as sensible a scheme as skinning our great men would be to prove their greatness.

c. These kings of the forest, the noblest of a noble race, rightly belong to the world, but as they are in California we cannot escape responsibility as their guardians. Fortunately the American people are equal to this trust . . . as soon as they see it and understand it.

d. The Tuolumne and Merced groves near Yosemite, the Dinky Creek grove, those of the General Grant National Park and the Sequoia National Park, with several outstanding groves that are nameless on the Kings, Kaweah, and Tule river basins, and included in the Sierra forest reservation, have of late years been partially protected by the Federal Government; while the well-known Mariposa Grove has long been guarded by the State.
