Let the digit in the ones place be x

Then,

the digit in lakhs place becomes 3x.

• Lets consider option (a) 836972

The ones digit is 2.

According to the condition, lakhs digit must be 3$\times$2 =6

But the lakhs digit given is 8

So, option (a) is incorrect

• Lets consider option (b) 326511

The ones digit is 1.

According to the condition, lakhs digit must be 3$\times$1 =3

Also the lakhs digit given as 3

So, option (b) satisfies this condition.

Option (b) is the correct option

• Lets consider option (c)746398

The ones digit is 8.

According to the condition, lakhs digit must be 3$\times$8 =24

So, option (c) is incorrect

• Lets consider option (d) 374218

The ones digit is 8.

According to the condition, lakhs digit must be 3$\times$8 =24

Lakhs digit cannot be a two digit number.
