Which sentence in this except from Mark Twain’s The Adventures of Tom Sawyer shows Tom to be resourceful?
Monday morning found Tom Sawyer miserable. Monday morning always found him so—because it began another week's slow suffering in school.
Tom lay thinking. Here was a vague possibility. He canvassed his system. No ailment was found, and he investigated again. This time he thought he could detect colicky symptoms, and he began to encourage them with considerable hope. But they soon grew feeble, and presently died wholly away. He reflected further. This was lucky; he was about to begin to groan, as a "starter," as he called it, when it occurred to him that if he came into court with that argument, his aunt would pull it out, and that would hurt. So he thought he would hold the tooth in reserve for the present, and seek further. So the boy eagerly drew his sore toe from under the sheet and held it up for inspection. But now he did not know the necessary symptoms. However, it seemed well worthwhile to chance it, so he fell to groaning with considerable spirit.
A. He generally began that day with wishing he had had no intervening holiday, it made the going into captivity and fetters again so much more odious.
B. Presently it occurred to him that he wished he was sick; then he could stay home from school.
C. Suddenly he discovered something. One of his upper front teeth was loose.
D. Nothing offered for some little time, and then he remembered hearing the doctor tell about a certain thing that laid up a patient for two or three weeks and threatened to make him lose a finger.
