The solemn butler knew and welcomed him; he was subjected to no stage of delay, but ushered direct from the door to the dining-room where dr. lanyon sat alone over his wine. this was a hearty, healthy, dapper, red-faced gentleman, with a shock of hair prematurely white, and a boisterous and decided manner. at sight of mr. utterson, he sprang up from his chair and welcomed him with both hands. the geniality, as was the way of the man, was somewhat theatrical to the eye; but it reposed on genuine feeling. how is dr. lanyon characterized in the excerpt? as friendly as arrogant as wise as mournful

Dr. Lanyon is characterized as friendly is this excerpt and we can find evidence in it to support the idea. The author uses adjectives to describe his appearance and personality so we can infer he is a friendly man. The adjectives that reflect this are: “hearty, dapper, boisterous and decided manner”.  Also the phrase “welcomed him with both hands” and “it reposed on genuine feeling” provides an idea of a sincere and friendly person.

Therefore, the other 3 options do not reflect the personality and appearance of Dr. Lanyon since there is no evidence in the text that Dr Lanyon is arrogant, wise or mournful.
