Explanation:
According to octet rule there should be 8 electrons in the atom's subshell/valence shell. Giving it the same electronic configuration as a noble gas.
among the options:
c) option is correct, as 5 bonds to carbon is violating the octet Rule, 5 bonds means 10 electrons exceeding the noble gas configuration and violets the octet rule.
All the other options are are incorrect, they are following

Explanation:
The volume is the same in both cases so the formula is
P1/T1 = P2/T2
T1 = 20 + 273 = 293 You have to convert Celcius to degrees Kelvin.
T2 = 65 + 273 = 338 degrees Kelvin
P1 = 2.0 atmospheres.
2.0 / 293 = P2/ 338
2*338 / 293 = P2
P2 = 676 / 293
P2 = 2.31 atmospheres
