When does centriole duplication take place?

Question

1. Late G1 and early S
2. Late S
3. Late S and early M
4. Early M and late G1
5. Early G1 and late S

Answer 1

"In mammalian cells, the centrosome consists of a pair of centrioles and amorphous pericentriolar material. The pair of centrioles, which are the core components of the centrosome, duplicate once per cell cycle. Centrosomes play a pivotal role in orchestrating the formation of the bipolar spindle during mitosis. Recent studies have linked centrosomal activity on centrioles or centriole-associated structures to cytokinesis and cell cycle progression through G1 into the S phase. In this study, we have identified centrobin as a centriole-associated protein that asymmetrically localizes to the daughter centriole. "

I read that as answer 1 (late G1 & early S), but I'm not certain.
