Find the Jaccard coefficient (Jc) for the query q and docs d1 and d2 below.

q: big data
d1: the problem of data duplication is very big.
d2: check important data driven applications.

- Jc(q,d1)=1/6, Jc(q,d2)=1/4
- Jc(q,d1)=0, Jc(q,d2)=1/4
- Jc(q,d1)=1/3, Jc(q,d2)=1/5
- Jc(q,d1)=1/4, Jc(q,d2)=1/6
1) Jc(q,d1)=1/6, Jc(q,d2)=1/4
2) Jc(q,d1)=0, Jc(q,d2)=1/4
3) Jc(q,d1)=1/3, Jc(q,d2)=1/5
4) Jc(q,d1)=1/4, Jc(q,d2)=1/6
