Read these lines: "It must be understood that neither by word nor deed had I given Fortunato cause to doubt my good will. I continued, as was my wont, to smile in his face, and he did not perceive that my smile now was at the thought of his immolation." As used in the quoted lines, "as was my wont" most nearly means

1. The verb the phrase attaches to is continued, which already means to go on doing something begun earlier. 2. The sentence before it says he had given no cause for doubt by word or deed, so the smiling was long established. 3. A phrase meaning custom or habit fits both signals, which is option C. 4. Option D would make the smile a change, but the whole point is that nothing visible changed. _Source: Edgar Allan Poe, The Cask of Amontillado, public domain_
