Transition elements form binary compoundswith halogens. Which of the following elements will form $M F_{3}$ type compounds?

(a) Cr

(b) Co

(d) Ni

Choose the correct option
1. (a, b)
2. (b, c)
3. (c, d)
4. (a, d)

Transition elements such as Cr and Co form binary compounds with halogens, i.e.,

C r F_{3} a n d C o F_{3}

whereas Cu and Ni do not form

C u F_{3} a n d N i F_{3}
