Which cephalic index value is associated with a dolicocephalic head shape?

Explanation:
Dolicocephalic describes a long, narrow head. The cephalic index is calculated as width divided by length and multiplied by 100. Because the skull is longer relative to its width in a dolicocephalic shape, the index is relatively low. Values typically considered dolicocephalic are below about 75. Among the options, 70% sits in that low range, indicating a long, narrow skull. In contrast, a high value like 85% points to brachycephaly (short and wide), while 75% is around the mid-range, closer to mesocephalic. Thus, 70% best represents dolicocephaly.
