What is the position of the element in the periodic table satisfying the electronic configuration (n-1) d1 n s2 for n=4

Question

What is the position of the element in the periodic table satisfying the electronic configuration (n-1) d1 n s2 for n=4 (A) 3rd period and 3rd group (B) 4th period and 4th group (C) 3 rd period and 2 nd group (D) 4th period and 3rd group

When n=4, the configuration will be [Ar] 18 3 d1 4 s2 and thus period is fourth and group no. is third.

Q. What is the position of the element in the periodic table satisfying the electronic configuration $(n - 1) d^{1} n s^{2}$ for $n = 4$

3rd period and 3rd group

4th period and 4th group

3 rd period and 2 nd group

4th period and 3rd group

When $n = 4$ , the configuration will be $[A r]^{18} 3 d^{1} 4 s^{2}$ and thus period is fourth and group no. is third.
